Answer 2

Answer:

The ratio of amplitude of response to that of the input called Gain.

Explanation:

The amplitude response is the ratio of output amplitude to input, usually a function of the frequency. Similarly, phase response is the phase of the output with the input as reference. The input is defined as zero phase.

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. To obtain the phase response, we take the arctan of the numerator, and subtract from it the arctan of the denominator.

The actual amplitude in any year, expressed as a proportion of the average amplitude taken over a long period is called the amplitude ratio. It affords a measure of departure from normal seasonal variation.

And The ratio of amplitude of response to that of the input called Gain.
