Hi!
I am using a vcd remote control and tsop1356 sensor to sense its signal.

i'm pressing the remote button all the time...so a continuous pulse is generated when the sensor faces the remote and a continuous 4.5v (logic 1) when not in orientation to the remote.

I want to convert the continuous pulse stream to logic 0 so that i can use this logic 0 signal to feed to microprocessor and perform some operation.

Pls suggest a circuit or some way to do this.
