Does capacitor banks produce harmonics?
No, capacitor banks reduce harmonics. They act like a low pass filter. They also raise voltage by compensating for inductance and bringing the power factor back closer to 1. Capacitor banks in the power system can cause transients when randomly closed - many utilities use zero voltage closing equipment, or inductors to counteract this short time harmonic problem.
Q factor of low pass filter?
The Q factor is describing how sharp the dropoff of the filter is relative to the pass band. Wikipedia has a decent writeup on Q factor. The more components you use to make the filter, and the lower the cutoff frequency, the higher the Q will be.
What difference between amplitude modulation and double sideband suppressed carrier?
Both are forms of AM but in suppressed carrier a filter is used to attenuate the carrier frequency prior to transmission. This is usually done to reduce the total transmitter power consumption. An ordinary AM radio cannot correctly receive suppressed carrier stations, you must have a receiver that replaces the carrier prior to the detector stage.

How do you design a harmonics filter?
With your hands.
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.
How can you filter harmonics from a square wave?
You can use a low-pass filter (passive is mostly coils) but you won't end up with a square wave.

What is the use of harmonic filter in capacitor bank?
harmonic filter capacitor is used to filterize the unwanted heat created by a certain component like power supply. harmonics are voltage or currents that operates a certain frequency. john

Advantages and disadvantages of chebyshev filter?
Advantages are getting a steeper decline in the band. Disadvantages are having more distortion in the wavelength frequency available.
