AF103 Description
The AF103 is a fourth order elliptic low pass filter designed to reject frequencies above 1200 Hz and pass signals· below 950 Hz. This filter is used to separate the low band of frequencies from the high band in a Dual Tone Multi Frequency (DTMF) Touch Tone® receiver. The unit is fully tuned and requires no external ponents - only power supply, input and output connections.
