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.
