Question

An active low pass filter (with op-amp), the capacitor value is 500 pf, the resistor value is 1kΩ and the input signal source is 20 V.

a)draw the complete circuit with the data provided in the example

b) plot the frequency response graph of the filter, use at least 5 dots for the plot of the graph and identify in it the pass band and the attenuation band.

c) determine the filter output voltage f = 100KHz and f = 1MHzy and compare the results obtained in the graph

d) plot the response chart in normalized frequency of the filter, use at least 5 data for the plot of the graph and identify in the same pass band and the attenuation band
