Hi all,
I've been experimenting with receiver circuits and I'm missing something. The LC receiver I have (one of Ming's) and the Microchip (433.92 MHz, rfRXD0420) seem to have noise at the output when they're not receiving a signal. I see the signal (on a scope) when I press a button in the respectively transmitter. But if I have this signal apply to the input of a micro, it looks like I'm going to decode something (wrong) all the time because of the noise. Shouldn't the output pin be low until the pulses are demodulated by the receiver ? So that a high or low transition could be used to trigger an IRQ and decode the signal ? As I said before... it looks like I'm missing something in between the RX module and the MPU.
Could someone shed some light into my information gap please ?
Thanks
