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...
Design a four-pole Chebychev bandpass filter which a passband of
4750 rads/sec to 5250 rad/s. The pass band must have a magnitude
between -0.5 and 0 db..
1) A student wants to design a low-pass Butterworth filter for a
data acquisition system that will not attenuate 2 Hz signal more
than 4 dB but will have more than 80 dB of attenuation at 50 Hz
signal.
(a) Determine the minimum number of filter stages required and
the cutoff frequency (in Hz) that can be used (For the cutoff
frequency, choose an integer number in the range)
(b) Assuming the source and load resistances are 50 Ω, draw...
1. (Short Answer)

with n-order Butterworth active filters?
b) Describe 2 benefits of using scaling factors in active
filters.
c) Explain the difference between Fourier series and Fourier
Transform.
d) Explain the difference between Laplace Transform and Fourier
Transform
e) Describe the procedure to obtain the Fourier Transform of no
convergence function.
f) Describe the conditions to use Fourier Series.
g) What are some limitations of high order active filters?
Create a 6th order Butterworth filter. Then change capacitor
values and notice how the design specifications change. Create a
plot where there is an ideal high performance filter (exact
capacitor values) compared to a filter where low tolerance
capacitors are used (the value of the capacitor drifts).
I need to obtain an approximate implementation of a Butterworth
low pass first order filter using P-spice. It suppose to have a
cutoff frequency of 1000Hz and the attenuation cutoff frequencies
fixed at 3db.
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.
