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.
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 first order, high pass active filter with a cutoff
frequency of 20 krad/sec. Cascade Four of this filter designed and
find reasonable values for the resistor and capacitor. Obtain the
transfer function and show a circuit schematic for your filter.
Plot the Bode plot
Design a state Variable Filter that has a corner frequency of
100 KHz and a quality factor (Q) of 20. Assume both the
frequency-determining resistors and capacitors are equal.
Design a Butterworth bandpass filter with the given
requirements:
10 dB stopband attenuation at 100 rad/sec and 900 rad/sec
1dB passband attenuation at 400 rad/sec and 600 rad/sec
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..
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...
