General Description
The AF102 is a fourth order elliptic highpass filter designed to reject frequencies below 650Hz.
This filter rejects the 350Hz and 440Hz dial tone frequencies present on a telephone line.
The unit is fully tuned and requires no external components - only input, output and power supply connections.
