Is digital signal frequency 0 Hz?

No, a digital signal does not have a specific frequency like an analog signal. Digital signals are represented by discrete values at specific time intervals and are typically transmitted using square waves with a fundamental frequency determined by the data rate.


What advantage do regenerative repeaters have when used for digital communication?

When any digital signal is transmitted over a pair of wires, it degrades in amplitude. Regenerative repeaters receives the incoming signal, extracts the clock, then regenerates the original signal as a clean digital square wave as if it was the original signal transmitted from the source. Thus the name repeater.


What is the difference between periodic and aperiodic signals?

A signal which repeats itself after a specific interval of time is called periodic signal. A signal which does not repeat itself after a specific interval of time is called aperiodic signal.A signals that repeats its pattern over a period is called periodic signal,A signal that does not repeats its pattern over a period is called aperiodic signal or non periodic.Both the Analog and Digital can be periodic or aperiodic. but in data communication periodic analog sigals and aperiodic digital signals are used.


What is pwm?

PWM stands for Pulse Width Modulation. It is a technique used to encode a message into a pulsing signal by varying the width of the pulse relative to a fixed time frame. PWM is commonly used in controlling the speed of motors, regulating power to LEDs, and generating analog voltage levels from digital signals.


What is an analog signal and a digital signal?

An analog signal is one which is continuous in time as well as continuous in amplitude . Example : sine wave, cosine wave. An Digital signal is one which is continuous in discrete in time. Example : square waves.

What is the difference between Analog signal and Binary signal?

An analog signal has a sine wave form and a binary signal has a block "wave" form. The binary signal is either on or off ("up" or "down"), and never anything in between. analog: http://img99.imageshack.us/img99/7723sineuk6.jpg binary: http://img154.imageshack.us/img154/1894binarypb6.png

the difference between them is that the bottom face is different one of them is a rectangle and one of them is a square


What is difference between pulse and square wave?

A pulse wave is a waveform where the signal switches between high and low levels at a consistent frequency, creating pulses of varying widths. A square wave is a type of pulse wave where the signal switches abruptly between two levels (high and low) at a fixed frequency, with the width of the pulses remaining constant.
