A: square wave can be positive and or negative. A digital signal is a square wave but it can be of invariable duty cycles
Algebraically if we have a number 'x^2' Then its square is (x^2)^2 = x^4 For the square root of x^2 = +/-x
Belgium has a population of 10 500 000, and an area of 30 300 square km New Zealand has a population of 4 300 000 and an area of 268 600 square km
Parasitic capacitance is the unwanted capacitance between: 1. A signal line and other signal line. 2. A signal line and earth. 3. A signal line and power supply line. Not that, I remember all (even most) of the effects, let me answer you with whatever I remember: 1. Unwanted coupling between two different signals, resulting in "crosstalk" between two signals. One signal interferes with other and other interferes with one. 2. attenuation / distortion of high frequency signals which have high impedance / limited current capability. 3. Ringing (unwanted oscillations) rising edge and falling edge of the signals rectangular / square wave.

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.
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.
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.
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.
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.
No mathematical difference.
There is no difference between square meters and meters square. for simplicity we use these in different form.
the difference between them is that the bottom face is different one of them is a rectangle and one of them is a square
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
It is the same as the difference between a blue square and a square.
the difference between them is that the bottom face is different one of them is a rectangle and one of them is a square
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.
