Question

In your design, please explicitly describe the transfer function, the bode plot, and the value of passive components obtained while designing the filter according to the given specification.

Use Multisim for the circuit design as well as frequency response analysis, and compare the output (Bode plots) with the simulation that can be obtained from MATLAB.

Validate your answer using MATLAB.

Design a bandpass passive filter to pass frequencies between 500 Hz and 1500 Hz.

Answer 1

clc;clear;

R1 = 3.185e3 ;

C1 = 100e - 9 ;

R2 = 106157 ;

C2 = 1e - 9 ;

G _ s = tf([20 0], [(1/R2*C2) (1 + (1/(R2*R1*C1*C2))) (1/R1*C1)])

bode(G_s)
