What is frequency response in signal processing?

In signal processing and electronics, the frequency response of a system is the quantitative measure of the magnitude and phase of the output as a function of input frequency.

Which function is used to get frequency response?

Frequency response function of a linear mechanical system is defined as the Fourier transform of the time domain response divided by the Fourier transform of the time domain input [1].

How many types of frequency response are there?

The frequency response of a mic is represented graphically by a response curve. The two most common types are flat response and shaped, or tailored, response.

What is the frequency response of a system and how is it determined?

A frequency response describes the steady-state response of a system to sinusoidal inputs of varying frequencies and lets control engineers analyze and design control systems in the frequency domain. To understand why the frequency domain is important consider an acoustic guitar.
