In Matlab, Design a model for a bandpass filter with a bandwidth
of 4000 Hz, and a center frequency as specied below. Once you have
the model, it is easy to programmatically change the center
frequency.
center frequency: 20 KHz, 24.5 KHz, 29 KHz, 33.5 KHz, 38 KHz,
42.5 KHz, 47 KHz

Design an active low-pass filter with a gain of 10 and that can
reject 120 Hz signals. What are the parameters for this design?
Please show all work. Thank you.
Design an active low pass filter with a corner frequency of 50 Hz and amplification of 10. Pick the values of the resistor and capacitor based on your own judgement to keep the cost reasonably low (simpler circuit design with less components is better).
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.
4)Design a band-pass filter with a passband from 500 Hz to 2000
Hz using “butter” routine of MATLAB. Assume a sampling frequency of
8KHz. Let the filter order be M=4. Plot the magnitude response and
provide the filter coefficients and the transfer function

off frequency of 8kHz using opamp
