Bandpass filter for digital TV antenna is to cut the ripple signal from band frequency TV reception on digital band between 470 MHZ - 800 MHz.
There are 2 kind of Bandpass filter.
1. RC Bandpass filter, which is using Resistor (R) and Capacitor (C) .
RC Bandpass filter is combination between Low Pass Filter and High Pass Filter.
For Low Pass Filter , we use R and C component :
R = 10 Ohm
C = 33. 88 pF
For High Pass Filter, We use :
R = 10 Ohm
C = 18.3 pF
