My receiver o/p has 3 leads - +V, GND and signal. I connected the signal lead to the resistor (7MΩ) connected to the capacitor (100µF). Then I have used IC7414 for schmitt trigger inverter. I have connected its o/p to IC 4081 AND gate. The other i/p for the AND gate is the signal lead itself. I have given o/p of the AND gate to the clock of HEF 4013 (pin 3), the signal lead itself to pin 5 and and took the o/p from pin 1.
Pin 14s of all ICs are connected to the 4.8V +Vcc and pin 7s to the ground leads from the receiver.
