A design example for a bandpass filter is shown below:
Assume the system design requires a bandpass filter with f
= 1kHz and Q = 50. What needs to be calculated are
capacitor and resistor values.
First choose convenient values for C
Then from Equation (11),
From Equation (12),
From the above calculated values, the midband gain is H
R

4.5 PULSE GENERATORS AND OSCILLATORS
A pulse generator is shown in Figure 16. Two diodes have
been used to separate the charge and discharge paths to
capacitor C.
