How to Build a Passive Bandpass Filter Circuit

http://www.learningaboutelectronics.com/Articles/Passive-bandpass-filter-circuit.php

The high-pass filter design creates the lower cutoff frequency point. In the circuit, we want the lower cutoff frequency point to be 1KHz. Therefore, the high-pass filter passes all frequencies above 1KHz. The formula for calculating the lower cutoff frequency is, frequency= 1/2πR1C1= 1/2π (150Ω) (1μF)= 1061 Hz≈ 1KHz.
