To activate a low pass filter of corner frequency about 106 KHz, activate the two right most ac supply and switch. Open the remaining two switches. Increase the frequency from say 200Hz to 1MHz to demonstrate the low pass property.
To activate a high pass filter of corner frequency about 7.234KHz , activate the two left most ac supply and switch. Open the remaining two switches. Increase the frequency from say 200Hz to 1MHz to demonstrate the high pass property.
To activate a band pass filter , activate the two left most ac supply and switch , the upper most switch and open the right most switch. Increase the frequency from say 200Hz to 1MHz to demonstrate the band pass property.
Observe and compare the ac supply voltage, the 220 Ohm resistor voltage, and the 1nF capacitor voltage.
