where for all three filters,

A design example for a bandpass filter is shown below:

Assume the system design requires a bandpass filter with f O = 1 kHz and Q = 50. What needs to be calculated

are capacitor and resistor values.

First choose convenient values for C1, R1 and R2:

C1 = 1200 pF

(26)

2R2 = R1 = 30 kΩ

(27)

Then from Equation 24,

(28)

From Equation 25,

(29)

From the above calculated values, the midband gain is H0 = R3/R2 = 100 (40 dB). The nearest 5% standard

values have been added to Figure 63.
