What is the use of magnitude response of system response?

In most cases, the magnitude response is the ratio of the amplitude of frequencies in the output signal to the amplitude of frequencies of the input signal. Usually, if we want to describe how a system impacts the amplitudes of frequencies in a signal, we will use the term magnitude response.

How do you find the magnitude of a frequency response?

First we substitute s = jω into H(s) to obtain an expression of the frequency response. Note that the numerator and the denomator are both complex. To obtain the amplitude response, we take the absolute value of H(jω). To do this, we evaluate the magnitude of the numerator and the denominator separately.

What is magnitude and phase response?

The minimal-phase response can be calculated from the amplitude response by using the Hilbert transform. The figure above shows the magnitude response of the complex transfer function between loudspeaker terminals and sound pressure at a point on axis in 1 m distance measured by TRF module using a shaped stimulus.
