Re: Receiver
Hi lads, Thanks for your reply.
Renwl: Yes, the signal is received by the photodiod.
Jim:
Yeah, it looks like that. I think the downconverted frequency is what charge/discharge the capacitor at the end to give a pulse. But the values seems odd to me. The reason is, the resonance...
Hi.
I have a problem understanding the circuit I have attached. As i understand, the signal that is received (in sinusodial form) is being "converted" to a pulse length depending on the incoming signal's frequency. Am I right on this? Can anyone explain me maybe in more detail about what is...
Hi,
I have a project for a speedometer that can detect a vehicle speed between 0 - 999 kph. I have been doing some research but i seem to run into the same problem nomatter what I do.
The Basic principle I'm using is the Doppler effect. This gives me a change of frequency in response and from...
