What are the Advantages of digital transmission over analog?
Hi,1) Digital signals do not get corrupted by noise etc. You are sending a series of numbers that represent the signal of interest (i.e. audio, video etc.)2) Digital signals typically use less bandwidth. This is just another way to say you can cram more information (audio, video) into the same space.3) Digital can be encrypted so that only the intended receiver can decode it (like pay per view video, secure telephone etc.)There are others, but this is three of the biggies.Hi!Following are the Advantages of Digital Transmission over analog transmission.1. The signal is exact. For example, Digital formats like PCM (Pulse Code Modulation) can hold the exact digital format of sounds.2. Digital signals can checked for errors. Generally, all digital transmission methods use 'head labels' to provide better checking facilities. Head label may contain how many packets may need to complete the transmission, what is the sequence number of each packet of data, acknowledgment labels etc.3. A variety of services can afford over one line. For example, IpTV connection can used to watch cable TV channels while browsing the Internet through a PC using same line. This line can also used to make a phone call at the same time.4. Digital data can be compressed and therefore possible to pass over higher bandwidths. Any digital data; data, image, video, voice can be compressed.5. More secure. Digital data can be encrypt using an encryption method. Only the dedicated receiver can decode the message.6. Supports data integrity. Simple to integrate voice, video and data. Digital transmission provides easier way to integrate different digital formats.7. Digital transmission provides higher maximum transmission rates via medium such as optical fibers. Typically, digital transmissions use less bandwidth.Hope this will help you!(H.W Thushara Indika from Bandarawela - Sri Lanka)
What does CITIfile mean?
CITIfile is a standardized data format that is used for exchanging data between different computers and instruments. CITIfile stands for Common Instrumentation Transfer and Interchange file format.
What is IEEE format?
IEEE is the acronym for Institute of Electrical and Electronics Engineers. It provides worldwide standards for the electronics industry. An IEEE format would therefore be a format accepted by the IEEE as universal.If you are talking about a IEEE format for works cited page in a formal paper, the format would be (for a chapter in a book with one author):1. P. Carter, "Electrics," In Backstage Handbook: an Illustrated Almanac of Technical Information. Louisville: Broadway Press, 1988, pp. 163-202.Note: Do not use italics.Cite all works in one list at the end of the paper, listing them in the order they appear in your paper. Do not repeat sources.When quoting or referencing a source, use brackets in the format [a: b]; where "a" is the citation number, and "b" is the page. If mentioning an author cited, bracket with the format [a] Example:Carter [1] believed that the lack of international color standardization was actually a boon to entertainment. The different colors provided by different gel manufacturers [1: 174] gave a wider field of options to lighting designers.For more complete information on IEEE formating, most college websites have complete (and EXHAUSTIVE) material on the subject such as "How to cite a webpage with more than three authors" and "How to cite an email from my dog who has no last name."
How do you convert NTSC signal into a computer signal?
The best way to convert an NTSC signal into a computer signal is with a TV Frame Grabber. Buy the board, install it, and it should be able to convert NTSC video into MPEG or some other video. You will even be able to do this from RF, off the air or off of cable - just understand that some countries are digital, instead of analog - but this answer is NTSC, which is analog. If you want to build the board yourself, consult the specifics of NTSC with google, wikipedia, or something - it is a complex task. In high level generalities, the process is... Build a sync separator that can differentiate between horizontal and vertical sync, and maintain the black and white reference levels. Build an interlace detector that can detect and process the equalization pulses that occur during vertical sync. These equalization pulses are used to identify the interlacing between 29.97 Hz frame rate and the 59.94 Hz field rate. Build a 3.58 MHz chroma oscillator that is phase locked to the chroma burst on the back porch of the horizontal sync. Scan the data portion of each horizontal line - you will need a hardware array for each bit cell... The luminance (black and white) data is the mean voltage between black and white reference levels at each bit cell. The color saturation data is the amplitude of the 3.58 Mhz subcarrier at each bit cell. The color hue data is the phase angle of the 3.58 MHz subcarrier at each bit cell. You will need to convert the stream of bit cell data into video pixels, and then convert that into whatever PC compatible format you want. Other things, such as closed captioning can be added by decoding the bit stream on various lines reserved for that during vertical sync. Again, buy the board - its easier - unless you want to make a semester project out of this.
How paper presentation in IEEE format on ethical hacking?
You will need to explain some of the points of ethical hacking. These can sometimes help a business to learn where weaknesses are.
What is the term for converting computer data from one format and saving it in another?
Transcoding is the term for converting computer data from one format to another. Transcoding can be analog to analog or digital to digital conversion.
Converting sound from continuous to discrete format is done with a?
analog to digital converter
What is the definition of in camera recording?
The process of converting a light signal through the CCD sensor of a camera, by converting the signal from analog to digital and storing in an electronic media, using a commonly accepted digital format, usable by any agreed platform
What is the meaning of digitization?
Digitization, or digitizing, is the process of converting information into a digital format. This includes storing files onto a computer, processing music that was recorded in an analog format to digital, and even creating documents and emails and then sending them over the Internet.
What is a transcode?
The conversion of analog video to a digital format, or vice-versa.
What is the process of converting data from encrypted format back to its original format?
Decryption is the process of converting data from an encrypted format back to its original state.
What piece of equipment is used to translate digital signals into analog format for delivery across analog links?
modem
How may analog media be converted to a digital format?
digital imaging (using digital cameras and scanners), sound cards, and analog video-capturing devices sample, compress, and convert analog media into a series of 0s and 1s (digital) signals for processing by a computer
Is PCM is an example of analog to digital?
No, Pulse Code Modulation is a communication method used to carry digital data but is not part of any analog to digital conversion. PCM is often used to carry audio data as a digital stream and therefore is the encoding used as the signal is first converted to a digital format.
What is the term for a device that converts digital data from a computer into analog signals and back again?
The devices are known very simply as analog to digital converters and digital to analog converters. They are frequently shorted to A-D and D-A converters. A complete analog to digital converter will not only convert the analog signal into a set of numbers, it will also format the digital data ready to deliver to the next step in the signal chain. In television, this means generating a fairly complex stream of data that will carry not only the picture but audio and other data as well. Digital to analog converters reverse the process and use the incoming data to generate an analog signal. In television, well know examples are the digital set top boxes. They receive digital data from an antenna and convert the numbers into analog audio and video signals.
What does it mean to be quantized?
Quantization refers to the process of approximating continuous values with discrete values. In physics, it often pertains to the quantization of physical quantities like energy or charge into discrete levels. In digital signal processing, quantization refers to converting analog signals into digital format by rounding or approximating data values to a set number of bits.
Is there an spdif analog audio out?
No, a S/PDIF is, by definition, a Sony / Phillips Digital Interconnect Format connector, and is always a digital signal. It is usually connected by an RCA cable, and can be carried by cable specified for analog use, but digital cable is better.
