saturation arithmetic eliminates limit cycle due to overflow, but it causes undesirable signal distortion due to the non linearity of the clipper.In order to limit the amount of non linear distortion , it is important to scale the input signal and the unit sample response between the input and any internal summing node in the system such that overflow becomes a rare event.

What do you need for the new digital tv signal?
A tv antenna and a digital tv and/or a converter box.
How do you connect 3 tv's to a new digital Ariel?
If all your TV's are digital, you just need to use a digital signal splitter. The question is, will you have enough signal to share among three TV's. If the pictures look snowy or you can't get a decent pix on any of them, you might need to add an antenna amplifier.
Do you need a stronger signal for digital TV or for analog TV?
There are two answers to the question - Digital or analog. Here is the reason why: Digital signal are very robust signals as long as they do not fall below a certain strength and quality. As long as the signal is above that threshold, a receiver should be able to interpret the data correctly. That means a full quality image even though the signal may only just be above the strength and quality threshold. Analog signals need a higher signal strength and quality to achieve full quality images at the receiver. As the signal strength and quality reduce, more noise and other distortion can be detected in the image. Despite this, a signal strength and quality far lower than an equivalent digital signal will still be received. The image may be degraded to the point where noise is intrusive, but the content can still be seen. Broadcasters take into account the differing requirements of digital television and will make efforts to ensure that the signals received are of sufficient quality to provide reliable programs. It is perhaps worth pointing out that signal strength and signal quality are two separate measurements. Quality is just as important as strength so signal strength alone will not guarantee good reception in all cases.
If you have a digital tv and an outdoor antennae do you need a converter box?
In the US the answer is probably not. Digital and analog TV broadcasts use the same frequencies and antennas. Digital TV is more fussy about signal quality than the older analog signals. So if you get marginal analog reception, figure on getting a new antenna for digital. The idea that there are special HDTV antennas is just marketing hype. Any antenna that gives you better digtial reception will also give you better digital reception.
My free view box doesn't work on my TV because I don't have an aerial on my house would an indoor aerial work?
It is unlikely that an indoor aerial will deliver a signal to drive a Freeview receiver. Digital television demands a good quality signal in order to decode it correctly. A poor analog signal would be shown by "snow" on the image. The same level of signal quality in a digital system would produce no picture at all. It might be worth trying an indoor aerial. You may be lucky enough to be in a strong signal area. If not, you may need to consider an external aerial.
Why is microphone useful?
Original.It changes the sound (pressure waves in the air in the room) into a digital signal.Correction:It changes the sound pressure waves into an ANALOG signal. Any digital signal is the result of feeding the analog mic signal into an analog-to-digital converter, typically in a computer's sound card.Original.An electric guitar doesn't need a microphone because it makes a digital signal.Correction:A simple guitar with magnetic pickups creates an ANALOG signal from the motion of the strings, typically tens to low hundreds of millivolts. If you want a digital signal, you need: 1. Analog-to-digital processing in the guitar itself, or2. Analog-to-digital processing externally, such as a computer sound card.Original.An mp3 recording is a digital signal.
Where should analog to digital converter be placed?
where an analog signal is to be converted into digital signal,because in some applications we need digital signal where we have analog signal that is we use an A/D converter
What do you need for the new digital tv signal?
A tv antenna and a digital tv and/or a converter box.
What is the need of digital image processing in nowadays?
i don't know and i don't need a friend to help me out
Why you need modems on digital circuits?
In digital circuits modem is used to multiplex and demultiplex the digital data.multiplexing means the digital signals amplitude or frequency or phase is varied with a carrier signal.at the receiver end the carrier signal is separated out and original digital signal is received
How can you convert the digital to analog or analog to digital?
Buy a new digital ready tv, get a digital receiver Sky or Freeview for your analogue tv
Would you use a analog multimeter to check the signal level of a digital circuit?
If its a very low frequency signal you might. A digital `signal` is still on and off voltages. If its too fast to see the meter changing then you need another method.
Will Comcast provide you with a digital TV antenna?
Comcast will provide you with a digital tv box that allows your television to receive the digital signal and therefore you won't need the digital tv antenna.
What is meant by sampling in analog to digital conversion?
while conversion of analog signal to digital signal, we need to convert continuous analog signal to discrete signal. this can be done by dividing the analog signal into specific time slots. this process is known as sampling. there is a condition for sampling that can be given as follows. fs<=2fm
Does a digital signal travel farther than an analog signal?
You need to make a distinction between analog and digital signals, and analog and digital data. Digital data can be sent on an analog signal by using a modem. Digital data sent on a digital signal is done over a wire using voltage pulses at two or more levels. Digital signals can't travel very far without amplifiers, but analog signals can cover huge distances, such as with satellite communications and even communications with deep space probes.
What are defrances between analog and digital?
The differences between analogue and digital is in the transmission of signals. Analogue technology will transmit a signal wave in its original format but in digital technology, the analogue wave is sampled and turned into numbers which are stored in digital devices.

If all your TV's are digital, you just need to use a digital signal splitter. The question is, will you have enough signal to share among three TV's. If the pictures look snowy or you can't get a decent pix on any of them, you might need to add an antenna amplifier.
