following specifications
Cut-off frequency, fo or fH = 2kHz
Maximally Flat, i.e. Q=1/√2
> Justify any assumption you make.
> Draw circuit with all designed values.
> Draw the frequency response (Gain magnitude only)
Butterworth filter
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...

The filter coefficients of a second-order digital IIR filter
are: a0 = 1, a1 = -2, a2 = 2, b0 = 1, b1 = 1/2, b2 = 1/8. (a's are
numerator coefficents and b's are the denominator coefficients).
Compute the magnitude response |H(ej?)| where ? = 2.721
rad/sec.
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.
