What is the magnitude of frequency response?

The frequency response is characterized by the magnitude, typically in decibels (dB) or as a generic amplitude of the dependent variable, and the phase, in radians or degrees, measured against frequency, in radian/s, Hertz (Hz) or as a fraction of the sampling frequency.

How do you calculate frequency response?

This can be solved for the frequency response, H(ω) = e ^jωn (b₁ + b₂ e ^-jω + b₃ e ^-2jω)/ e ^jωn (a₁ + a₂ e ^-jω + a₃ e ^-2jω). This form of the frequency response can be generalized to LTI difference equations with an arbitrary number of terms.

How to calculate the magnitude and phase of a transfer function?

To find the magnitude of the output, simply multiply the magnitude of the input (A) by the magnitude of the transfer function (M). The phase of the output is sum of the input phase (φ) and the phase of the transfer function (θ).
