The circuit is wired as follows
Now the input frequency is changed using the function generator and the output voltage is noted for the given frequencies
The graph was then plotted.
From the graph, we can say that the circuit behaves as a low pass filter as it passes low frequencies and stops high frequencies

QUESTION 1 Barry the Biologist has asked for your help to build an amplifier and filter to take small signals from his bird sensing microphones and amplify them so that he can capture the signals on his PC. The microphone produces AC signals at varying frequencies with 10 mV magnitude. His PC requires the signals to be 1 V magnitude. The signals that Barry is interested in are above 1 kHz Hz. He would like the filter to attenuate signals...
QUESTION 1 Anna the Audiophile has asked for your help to build an amplifier and filter to take small signals from her hifi system and amplify them so that she can drive her new subwoofer. The hifi system produces AC signals at varying frequencies with 250mVrms maximum magnitude Her subwoofer requires the signals to be 20 Vrms maximum magnitude. The signals that Anna is interested in are below 200 Hz. She would like the filter to attenuate signals at frequencies...

3. You have bought a data acquisition device from Ebay. The sampling interval of the device is 1 msec. a. What is the sampling frequency of the device? What is the folding frequency of the device? Now, you are measuring following sinusoidal signals with the data acquisition device. For each signal, draw 1) Fourier transform magnitude of the original continuous-time signal, 2) Fourier transform magnitude of the sampled signal (draw at least first positive replica and first negative replica), 3)...
For each filter mentioned in the following cases, first simulate the circuit using Multisim. You can get a plot of the transfer function that is called the Bode plot. From the right toolbar, select "Bode Plotter". Change initial (I) and final (F frequencies to 1Hz and 200 KHz, respectively. Use a Voltage AC source as the input signal. You do not need to change any parameter from voltage AC source Connect "Bode Plotter" to input and output of your circuit...
