and is used to characterize the dynamics of the system. It is a measure of magnitude and phase of the output as a function of frequency, doubling the amplitude of the input will double the amplitude of the output. In addition, Frequency response is the quantitative measure of the output spectrum of a system or device in response to a stimulus, if a sine wave is injected into a system at a given frequency, if the system is time-invariant, in comparison to the input. In simplest terms, then the frequency response also will not vary with time.
