Question

Design and draw a simple electrical circuit (a combination of a low-pass and a high-pass filter circuits) that will act as a bandpass filter for frequencies between 0.1 and 100 rad/s. Generate the magnitude Bode plot on matlab!!!

Please do the matlab! thank you!

Answer #1

Draw the circuit of second order low pass Butterworth filter and
design it at a high cutoff frequency of 1KHz. Draw the frequency
response of the designed filter.

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.

MATLAB. Design your own low-pass shelving filter which can boost
the low frequency of given music signal. After designing filter,
apply the filter to the original music signal and observe the
result. Include following plots.
A. Magnitude and phase plot of your filter.
B. Magnitude plot of original signal
C. Magnitude plot of filtered signal

1. Design a second-orderactive low-pass filter to amplify the
frequencies below 1 kHzwith gain of Av=150.Sketch the circuit and

What is the relationship between the poles of a high
pass and low pass filter and the cut off frequency? How do I design
a circuit that gives a specific cut off? for instance, an active
high pass first order filter with a cut off frequency of
100khz?
