What is square wave input?
It is a square shape of the wave applied at the input of the circuitry> ANSWER: A square wave is basically two rectangular power input It is called square to differentiate from other sources triangular sawtooth and so forth.
What is the meant by harmonic distortion in wave analyzers?
distortion refers to any deviation in any parameter like amplitude,time shape of an electrical signal from an ideal input signal.the distortion occurs due to the inherent non-linear characteristics of the component and devices that form the electronic circuit cause some harmonics to take place in the waveform and resultant deviation is know as harmonic distortion.
Write a program that input a positive integer and prints a triangle using for loop?
write a program that reads in the size of the side of square and then pints a hollow square of that size out of asterisks and blanks?
Why differentiator only produce a square wave?
It doesn't. It can produce any waveform if you feed the integral of the desired waveform into the differentiator's input.
What does bias mean in an electrical circuit?
Bias is a permanent voltage, applied to the input of an amplifier device, in order to make it work in the correct area of an amplification curve. Valves (thermionic tubes) and semiconductors (transistors) both use bias in their grid or base connection. A negative swing in the input could put the control input below the working of the device and cause it to switch off. This is undesirable as it will show as distortion. The bias raises the zero point, so that the signal will not turn the device off.
What is Class B push-pull amplifier?
When we get amplifier output current for 180 degrees of input. then it's called B class amplifier. In a push pull class B amplifier one of the two power transistors or other amplifying elements handles the positive half of the waveform and the other element handles the negative half of the waveform. In practice, push pull audio amplifiers are usually class AB; each power transistor handles slightly more than 180 degrees of input. This minimizes distortion (crossover distortion) when one of the two transistors ceases output and the other takes over.
Why a high input impedance?
A circuit (an amplifier) typically has a high input impedance so that it does not unduly load the input circuit. Any such load could cause distortion, and that is generally not desired.
Which class of amplifier have maximum distortion?
Class C since output cycle is less than 90 degrees for a full input. But it has highest power gain going upto 98%. And the exact term used for distortion is Total Harmonic Distortion since the distortion produced will be in multiples of the fundamental frequencies.
What is distortion in analog electronics?
If you feed a sine wave through an amplifier that isn't exactly linear, the output will be distorted, not a pure sine wave. Distortion is the defect where the output from a device does not mirror the input.
What is a distortion analyzer?
A distortion analyzer is an electronic test instrument that measures the accuracy of an electronic circuit at reproducing a wave. For instance, an audio amplifier might have a sine wave input to it, and the distortion analyzer measures how close the output is to a sine wave. If the output is clipped, the wave will be distorted, and the analyzer will measure the amount of harmonics present. The analyzer does this by supplying a low distortion sine wave test signal which is connected to the device under test. The output from the device is connected to the input of the analyzer where the original input signal is filter out with a precision notch filter. Anything left over after filtering represents distortion components and noise. Amplifiers will frequently have a "Total Harmonic Distortion plus Noise" specification which is an accurate term for the quantity measured by a distortion analyzer. There are many manufacturers of distortion analyzers. The Hewlett-Packard models 331a and 333 are laboratory standard instruments. Other notable manufacturers are Sound Technology Corporation and Textronix.
What is Class b power amplifier?

What does an X on the input to a hub represent?
You will see an "X" on many of the switch and hub input ports, indicating that this is a crossover connected input. This means that transmit and receive pairs are internally swapped to maintain proper signal alignment of the TX and RX pairs.

What if your Big Screen has a wavy distortion?
Need a lot more info to answer this...what kind of TV is it? CRT, LCD, Plasma, Rear Projection, DLP? Does every input cause distortion? What if you open the TV menu through the remote, is that also wavy?
What does quadrate mean?
Quadratic refers to a type of math function that is growing as a square of the input
What is meant by harmonic distortion in amplifiers?
Harmonic distortion is most simply characterised by an output which is not proportional to the input, but can be derived from the input by some function or other.Outputs which bear no relation to the input are instanced by noise, hum, motor-boating, or crackles, and are not harmonic distortion.Distorted outputs which are related to the input are in practice mostly due to a non-linearity in one or more stages, an overdrive condition, or an unbalanced phase splitting process before a push-pull output stage.Note. people have spent their whole lives on this, and books have been written.
