Question

Design a second order (two pole) low-pass filter for the following specifications

Cut-off frequency, f_{o} or f_{H} = 8kHz

Maximally Flat, i.e. Q=1/√2

> Justify any assumption you make.

> Draw circuit with all designed values.

> Draw the frequency response (Gain magnitude only)

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.

Design an active-RC low pass second order Butterworth filter for
a cutoff frequency of 1 kHz, and a pass band gain of 2 V/V. Use a
741 Op Amp. If using Table I, use a capacitor value of 0.1 μF for C
and C1, otherwise you may use any capacitors available in the lab.
If applicable, make an excel worksheet showing the calculations
required for the above design. Choose appropriate real
resistor values for the designed circuit and simulate this circuit...

Design a second-order Butterworth high-pass filter with an
infinite frequency gain of 0 dB and a -3 dB frequency of 5.24 kHz.
(include circuit design w/ component values)

What is cut-off frequency and how to calculate for low pass
filter?

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?

Design a two pole low pass Butterworth active filter using a
unity gain section to achieve a 3dB frequency of 1kHz. Select the
two filter resistances as 10k (ohms) each.

1. Design a second-orderactive low-pass filter to amplify the
frequencies below 1 kHzwith gain of Av=150.Sketch the circuit and
determine the component values.
2.Design a second-order active high-pass filter to amplify the
frequencies above 500 Hzwith gain of Av=100.Sketch the circuit and
determine the component values.
3.Design a second-order active band-pass filter to amplify the
frequencies between 500?1000 Hz with gain of Av=200.Sketch the
circuit and determine the component values

Draw a 2nd order low pass filter with a flat passband gain of 5
to remove the harmonic content of a 60 HZ square wave of triangular
wave input. Design for a cut off frequency of 80 Hz. Use 50 K Ohm
for the input resistance. Verify your answers using AC Sweep in
PSPICE

Please show steps. Thank you
Design an identical cascade unit gain active RC low pass filter
of order 4. The cut frequency for the filter is 800Hz. Use 1.0uF
capacitors.
a) Draw the circuit and calculate the values of R.
b) Express the transfer function of the filter H(s).
c) Plot the Bode diagram of the frequency response of the
filter.
d) Estimate the output voltage if the filter is excited with an
input voltage vi(t) = sin(15000t)
e) What...

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!
