I am using this IR receiver in a circuit, and I have noticed that sometimes the unit generates an oscillating output when it is not being activated by a remote - I am guessing that this is due to the USB power supply.
I have seen other threads talking about 'filtering' the power supply with a cap and a resistor - however, could somebody explain how they come about calculating what size cap and resistor are required - and how they actually achieve the 'ripple filtering' effect?
For examples sake, my IR receiver is powered by 5v, directly from a netduino - and generates output pulses (when activated by infrared) in the 0.5-4.5ms range (see image: I dont know if that information is required, but there it is).
