Figure shows a typical circuit for low-pass filter. An AC input Vi = 10 mV is applied at the left end and the output V0 is received at the right end. Find the output voltages for V = 10 k Hz, 100 kHz, 1.0 MHz and 10.0 MHz. Note that as the frequency is increased the output decreases and hence the name low-pass filter. |
