Audio Tone Generator and Detector

Audio Tone Generator and Detector

This unit has two seperate sections, a 2 channel audio oscillator generator and a dual tone detector receiver. One
audio oscillator operates at 1000 Hz and the other at 2000 Hz. The receiver side will accept a audio input and detect if there is a 1KHz or 2KHz tone. When 1KHz is detected the
output connector will have the pins 1 and 2 connected together through a relay. Also if a 2 KHz tone is detected
then pins 1 and 3 will be connected.
