a)Design a 5th order low pass Butterworth low-pass filter with a
cut-off frequency of 1592 Hz and a dc gain of 3dB. Find and present
the mathematical transfer function of the filter, showing all your
steps.
b) Write a Matlab code to plot the magnitude of this function
with a linear scale in dB units on the ordinate, and a log scale of
frequency on the abscissa.
The plot range should be: ordinate- linear scale from -100dB to...

a. Design a broadband Butterworth bandpass filter with a lower
cutoff frequency of 500 Hz and an upper cutoff frequency of 4500
Hz. The passband gain of the filter is 20 dB. The gain should be
down at least 15 dB at 200 Hz and 11.25 kHz. Use 20 nF capacitors
in the high-pass circuit and 10 k\Omega resistors in the low-pass
circuit.
b) Draw a circuit diagram of the filter and label all the
components.
Design a bandstop filter with a cutoff frequency of -3dB at W1 =
100 rad/s and W2 = 10,000rad/s. Confirm by plotting the magnitude
and phase of the transfer function in matlab.
Using a general Op-Amp 741, design a first order and a
second-order low-pass filter with cut off frequent of 5kHz. Subject
sinusoidal inputs with frequency from 1kHz to 10kHz and plot the
frequency responses for both the filters and provide your
opinion.
