gn than Matlab design. That's why the difference the results between PSPICE design and theory is larger than one of Matlab design and theory.
4.2 RC Filter (Passive Filter)
① Analysis how much the value of R and C be assigned to make gain close to 1 when designing 1st order passive HPF.
The equation of 1st order passive HPF = .
The interpretation of the equation is , so (gain) is .
After all, we just need to decide the affordable values of R & C to make RC close to 1, in other words, to make gain close to 1.
As for me, I chose C = 0.33uF & R = 3kohm.
The graph show that gain is close to 1.
