ABSTRACT:
The circuit includes a super regenerative detector (12) for receiving a modulated radio frequency signal from a transmitter. The output of the super regenerative detector is amplified and sent into a high frequency interpreter circuit (16, 18, 20) which de-modulates the signal creating an output of low frequency equal to the consecutive pulses frequency. The low frequency signal is received by a low frequency interpreter circuit (22, 24, 26) which outputs a digital signal of a single duration which is received by a counter circuit (30). The counter circuit (30) controls the firing of a triac (T1) to create lighting conditions of on, off and dimming.
