thank you very much!!! Finally I'm starting to make sense of this circuit.
i just seacrh on google for crystal oscillator n there are loads of them...some for some kinda clock counter and some for coverter or somethin like dat. My questions are
1) is there a particular type of crystal oscillator needed for the task at hand or do i need to design and build a circuit for this or can i just buy one?
if i can buy one..is there any speification i need to know about?
2) when uisng signal generator as u explained above, do i need to set both the "audio tone" and the "RF signal's frequency" or re they mutualy exclusive? (sorry I havent used one before...lol)
3) Also, i was talking to a friend and he said a crystl oscillator can aso be used as the external oscillator ciruit that controls the internal one... UR COMMENT ON THIS WILL BE GREATLY APPRECIATED!
Thanks
