Using ControlSystemsBase, DSP: Exemplary Use Case of Electronic Filter Design

Hi

Today, I have been experimenting with basic functions from the ControlSystemsBase.jl and DSP.jl packages. Some guidance for the below mentioned approach would be appreciated.

Given the simple transfer function T=Vout​/Vin​, where Vin​=sin(2πwx) and Vout​=Vin​/(RCs+1), I would like to find the filter coefficients to obtain the characteristics of a Butterworth high-pass filter with a cutoff frequency of, let us say, 1 MHz. Based on those coefficients, I want to define the variables R and C.

Have you seen this section of the docs?
