Design a first order, high pass active filter with a cutoff frequency of 20 krad/sec. Cascade Four of this filter designed and find reasonable values for the resistor and capacitor. Obtain the transfer function and show a circuit schematic for your filter. Plot the Bode plot
%% modeling the 4 stage casecade filter TF
s=tf('s');
T = (0.005*s)^4/(0.005*s + 1)^4;
%% generate the bode plot with margins
bode(T)
margin(T)
The output response of the bode plot is shown below
