A quick question before i get started:
1. Are there anything photo diode ic's packaged that can demodulate a 9 khz signal.
I need to be able to detect NIR pulses that are pulse modulated at 9 Khz. I have used NIR demodulation IC's such as the panasonic PNA4612 package that demodulates at 38 khz. What would be the best recommended method in building a circuit if i need to build one discretely to do detect a 9khz signal?
2. Is there a preferred method or circuit to detect pulses at a given frequency.
