I'm currently working on an infrared sensor system in which the output from the infrared receiver will be sent to a PIC32 microprocessor. I'd like to send that output signal through some simple signal conditioning hardware to protect the PIC32 from receiving a "false-positive" signal.

What would be the best way to go about this? Voltage Comparator with operational amplifier? Voltage Clamp? Simple Hardware Filter? The output voltage in question will be on the scale of between 1V and 10V.

Any insight would be greatly appreciated.

Have you considered using software to debounce the signal coming into the PIC32? You may be able to avoid the addition of external filtering that way.
