Question

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.

Answer #1

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)

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.

Using 5 nF capacitors and ideal op amps, design a high-pass
unitygain Butterworth filter with a cutoff frequency of 4 kHz and a
gain of at least -32 dB at 800 Hz. 30 points a) Draw a circuit
diagram of the filter and label all the component values.

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.

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!

(ii) R = X_L
(iii) the frequency is...

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?

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

Design a Butterworth Sallen-Key Low Pass Filter with the
critical frequency, fc = 7.23 kHz. For design
simplification in RC network, assume equal value for capacitor, C =
22nF while R has a ratio, m = 2. Use the quality factor, Q value
from the Table .
