How the frequency response of an audio amplifier can be determined using square waves?

If the square wave gets distorted a lot, then the frequency response is not good.To get more precise data, you really should not use square waves; since you want the frequency response, you need to test how the amplifier reacts to pure waves (sine waves) of different frequencies.

What waveform is best and why?
different waveforms are used for different purposes i.e a sinewave can be used to test the frequency response of an audio amplifier or act as a 'trace' signal to find a fault in an audio amplifier. Square waves can be used in digital circuits as a pulse or as a binary code.
How can you design a square root amplifier?
Logamp into an antilogamp
What do oscillators do?
Oscillators produce a waveform (mostly sine or square waves) of desired amplitude and frequency. They can take input from the output itself. For a complete oscillator circuit we require a feedback device, amplifier and feedback factor.
What does mono phase mean in electrical engineering?
mono phase probably means that you're using a linear phase response filter or delay meaning that all your frequency components get the same delay. Think of a square wave in the frequency domain, and how delay of reactive systems are a function of frequency
What is the formula for the length of a square?
The length of a square is not determined by a formula, it is determined by measuring the square.
What is the operating frequency of square wave generator?
A square wave can be generated at the same frequency as essentially any other waveform can.
How does the frequency vary with the length of a pendulum?
The frequency of a pendulum varies with the square of the length.
Why it is unsuitable for operational-amplifier to connect in open loop?
In open loop configuration the gain of the amplifier will be infinite, which in turn produces only square wave output.
What is the relationship of the frequency with the fundamental in the square wave frequency response?
The natural frequency of the spring refers to its frequency when hit or struck. Its lowest frequency is called fundamental frequency. For a spring, the 1st mode of natural frequency is fundamental frequency.
How does frequency of a pendulum vary with its length?
The frequency of a pendulum is inversely proportional to the square root of its length.
What has a higher frequency than fundamental frequency?
A square wave contains many higher harmonics of the fundamental. A much higher frequency, a harmonic of the fundamental, is what causes the fast slew rate of the square wave edges
What is square wave oscillators?
A square wave oscillator is a device which generate the square wave. the circuit of squre wave oscillator can be made by using operational amplifier(uA746) or timer IC 555 and also by other methods.The frequency depends upon the value of R and C inside the circuit. ANSWER: It is a test equipment designed to provide a rectangle waveform from x volts maximum to x volts minimum.
