Aim:
To study (a) the voltage gain as a function of frequency for low pass filter, (b) the
voltage gain as a function of frequency for high pass filter and © determine the phase shift
in an all pass filter.
Procedure:
1. For the low pass filter, make the circuit as shown in Fig. 6.1 Study and plot the voltage
gain as a function of the frequency. Calculate the allowed frequency band for the low
pass filter.
2. For the high pass filter, make the circuit as shown in Fig. 6.2 Study and plot the voltage
gain as a function of the frequency. Calculate the allowed frequency band for the high
pass filter.
3. For the all pass filter, make the circuit as shown in Fig. 6.3 Study and plot the phase shift
as a function of the frequency.
