What is the best method of data processing?
There are different methods of data processing. Some methods are manual data processing, mechanical data processing, online processing, batch processing and electrical data processing.
What is Analog carrier system used in telephony?
Analog Carrier System is a transmission system that uses repeaters that compensate for analog medium impairments, and produce output signals that are linear-scaled versions of input signals. Analog carrier systems can carry speech, data, video and supervisory signals although they are best suited for speech signals.
Where is digital data converted to analog?
A digital to analog converter, or DAC, is a device that takes a digital input, usually a word of some size, such as 8 or 16 bits, and converts the value of that word into some analog value, either a voltage or a current.
Can you split a scart output into two outputs?
A scart connector is a 21 pin rectangular connector that carries video, audio and control links between video recorders, DVD player etc and televisions. They have been popular for many years in Europe but are now giving way to HDMI as the new digital video interface becomes the accepted standard. As with all analog video signals, the video signals carried by the connector are designed as a point to point signal. Splitting a video signal and connecting to two inputs will load the signal and reduce the voltage level of the signal at both inputs. At best, this will reduce the image quality and may cause the image to fail completely. Although it is unlikely to damage the source equipment, it is not recommended practice. The audio content on the other hand can be split and taken to two inputs without any noticeable change to the audio performance. The best way to split a signal on a scart connector is to take the video content through a video distribution amplifier. The amplifier will then drive each of the inputs correctly and retain the voltage levels required. Although many television stores will not stock VDAs, they can be found though most audio visual dealers either online or local stores.
How can you use an analog telephone signal to activate a digital relay?
There are many different ways this could be done depending on the purpose and exactly which analog telephone signal is to be used.ring signal, this is a 120VAC 5Hz pulsed signal present between tip & ring when the phone is on hook and being called; a high voltage insulated optocoupler must be used to trigger a oneshot or flipflop that will control a relay driver to operate the relayon/off hook switching, when on hook 48VDC is present between tip & ring, when off hook this voltage drops below about 10VDC; these states are probably best sensed using a level detector on a floating power supply (to protect against damage by the ring signal) and a high voltage insulated optocoupler must be used to control a relay driver to operate the relayAF tone signal, this is a signal somewhere between 50Hz and 3KHz; a 600 ohm to 600 ohm transformer should be used to block the ring signal and DC on/off hook voltages, this transformer should drive an amplifier (and maybe a clipper) the output of which goes to one or more phase locked loops set to specific frequencies, the phase locked loop outputs each control separate relay drivers to operate the relaysNote: these are not the only way to accomplish this, in fact commercial off the shelf phone interface modules are available that will handle the ring and hook signals for you (maybe even including the relay drivers or even actual relays) and provide the AF signal ready to feed to the phase locked loops. Such modules may actually be the best way to start if you don't want to run the risk of a mistake that might cause the phone company to disconnect service for a detected fault that could damage their equipment.
Which is the best text book for digital signal processing?

Exampl for analog communication?
In Analog communication, the analog message signal modulates some high carrier frequency inside the transmitter to produce modulated signal.this modulated signal is then transmitted with the help of a transmitting antenna to travel through the transmission channel. At the receiver, this modulated signal is received and processed to recover the original message signal. Example: AM , FM radio transmission an TV transmission.
How can you receive regular analog stations with a converter box?
this will depend on your area of living. check your local tv station for your best signal. also analog is going away so you cant really get a analog station.. that's why the converter box is for to receive digital transmitions
Lexmark X5320 fax machine support digital dial tone?
Not to the best of my knowledge you would still require an analog phone signal.
Is digital electronics is the best or analog electronics?
They have their own merits and demerits you can't say digital electronics is best because in real world everything is available in analog quantity. Although Digital electronics is more reliable in comparison of analog because there is very high reliability in the sense (effect of noise) and correction of errors that occurred during transmission of digital signal, while this is not possible in analog communication.
What is Source of problem?
Finding the source of the problem can usually be accomplished with source separation. This is the best way to narrow the source in digital signal processing.
Are tivo's compatible with HD tv's?
Tivo's are compatible with HDTV with many combinations of hardware and performance. # Tivo's HDseries3 records and plays back HDTV signals for best HDTV experience. You need the HD signal from satellite, cable, or (antenna) channels. The series3 has the HDTV format NTSC tuner and is reverse compatible with the old analog ATSC tuner capabilities. # The FCC mandated that all DVDR'S manufactured after March 2007 be HDTV compatible. TIVO ended series2 production and responded with the series3. # Tivo series2 records and plays back the standard analog ATSC signal for non-HDTV viewing. Your HDTV must have an analog input capability or analog tuner to view the lower quality analog signal. You need the analog signal from your satellite, cable, or local broadcast (antenna) channels. Series2 devices only have the ATSC tuner. # Satellite and cable providers will promote the new HDTV format but will continue to provide the lower quality analog signals in their packages. You need want the HDTV package view HD quality programs. A series2 Tivo will only store and replay the lower quality analog signals. # Feb 2009 the analog signal channels will no longer be locally broadcast by antenna. The FCC is administering a program to provide each household a converter to modifying the HDTV signal to the lesser quality analog channels. You will need this converter to continue using the Tivo series2 with antenna supplied signals. The question then becomes, WILL TIVO SUPPORT THE SERIES 2 DEVICES WITH PROGRAM GUIDE INFORMATION?

What is analog device?
Analog devices are machines and components that react or work in a linear manner, often with an ability to make a continuous change. For example, a volume knob on a radio could be an analog device because it controls audio power output over a continuous range. Many amplifiers, power supplies, and radios use analog devices for generating or processing analog signals. Digital devices are machines and components that are always found in one specific state or another, rather than in some range between two points. Many analog and digital systems are designed to simulate the best features found in the other type of system, e.g., analog controls on a digital CD player, or digital controls on an analog radio.
What is the best signal between analog and digital?
This is a difficult question to answer. Digital signals in television and audio are hailed as the "best" quality but there are many factors that affect the quality of both analog and digital signals. Digital signals are not prone to quality loss once they are in a digital form. The data that makes up the signal can normally be stored, transmitted and received without error so the quality will be identical from start to finish. Analog signals can suffer from interference and losses which increase with the length of transmission line and with every active process used as the signal is stored and delivered. Therefore, in terms of quality loss, digital is likely to be the better medium. Digital signals in video and audio are frequently compressed. Raw HD data needs a data rate of 1500 megabits per second but broadcasters frequently compress an HD signal to as little as 6 megabits per second. The compression process inevitably results in a loss of detail and a loss of quality. SD data rates are 270 megabits as an uncompressed signal but are compressed to as little as 1-2 megabits for broadcast. Again, the signal quality suffers. Analog signals are always broadcast as full bandwidth signals so they do not suffer from quality loss due to compression. The final judgment regarding the best signal must be based on the quality of image seen. Without doubt, digital signal processing can deliver quality that most analog signals can never achieve but in reality, that is not always the case. Highly compressed digital television signals can often show a variety of unpleasant effects such as jerky movement and large blocks of the image without detail. As broadcasters devote more bandwidth to digital signals, the quality will improve but the quality is dependent on sufficient bandwidth for each signal. There will be many differing opinions on this topic but it must always be accepted that "digital" does not automatically mean "better".
