Question

Design a passive, first-order band-pass filter with a bandwidth of
4 decades centered at 1 krad/s.

Answer #1

Is it possible to acquire a passive band-pass filter by
cascading a passive high pass filter with a passive low pass
filter. Please explain.

Design a band-pass or band-rejection filter satisfying the
following requirements:
1-Central Frequency 10 kHz
2-Bandwidth 1 kHz
3-Gain of 20 dB or higher
and then do the hand calculations and Gain versus frequency
plots with 3 dB markdown.

Design a passive RC high pass filter with a cutoff frequency of
470 Hz using a 270 pF capacitor.
What is the value of the resistor? Express your answer with the
appropriate units.
What is the transfer function of the filter? Express your answer
in terms of the variables R, C, and s.
If the filter is loaded with a resistor whose value is the same
as the resistor in part B, what is the transfer function of this
loaded...

To analyze and design a passive, second-order bandreject filter
using a series RLC circuit.
A bandreject filter is needed for an equalizer, a device that
allows one to select the level of amplification of sounds within a
specific frequency band while not affecting the sounds outside that
band. The filter should pass frequencies lower than 1.4 kHz and
have a resonant frequency of 3.8 kHz. A 5.0 μF capacitor
and any needed resistors and inductors are available to be used...

Second order circuit as a band pass filter.
1. Consider a series RLC circuit of your choice with AC source.
Find the resonance conditions (resonant frequency, quality factor
cut-off frequencies and bandwidth.
Simulate(multisim) the resonance condition by experimenting with
AC signal of several different frequencies and comparing the output
amplitudes. You need to show graphs of simulation with several
different frequencies. Demonstrate that the simulation results
confirm the calculated resonance effect.
Make a band pass filter from circuit in (1)....

Design a FIR filter using the Kaizer window method for the
sepcifications:
Edge of pass band = 0.2π
Edge of stop band = 0.3π
Pass band ripple = 0.25 dB
Minimum stopband attenuation = 50 dB

Design a second-order band-pass filter to select the frequency
range of 36khz +/- 20kHz.
With the aid of a gain and phase plot, explain how an unwanted
oscillation can be avoided to attain stability.
Provide a statement on what condition an oscillation occurs.
Provide values of all components to the nearest standard (E24)
resistor values (+/-5% tolerance) and capacitor values (+/-10%
tolerance).

Design a Butterworth high pass filter which is 4th
order. The first element of the low pass
prototype shall be a capacitor
C1
. The 3 dB cutoff shall be 500 KHz.

circuit and determine the component values

PLEASE ANSWER QUESTION #2
Design an FIR band-pass filter with cutoff frequencies of π/ 4
and π/ 6 . The filter’s impulse response should have 81 samples
(i.e. N = 81). Use a Blackman filter window.
(a) Plot the filter’s impulse response
(b) Plot the magnitude of the filter’s frequency response, in
