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.

What is the frequency response?

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.

How do you find the frequency response of a LTI system?

−jΩm = C(Ω) − jS(Ω) = H(Ω) . , where H(Ω) is the frequency response of the LTI system. The system therefore produces an output signal that is the “3-point weighted moving average” of the input.
