Hello every one,
I have just registered and i have questions already :D

Well, am working on a project and am so stuck. Am working on a Superheterodyne AM receiver. I have been asked to pick 2 frequencies 900 and 980 KHZ and design the receiver so it would output these 2 frequencies automaticaly or digitaly.

Am kinda done working on the amps, but i thought i should use a VCO instead of the regular oscillator i have so it would pick the frequencies i want.
The thing is i never designed a VCO. and dont know how to do so.

If anyone could help me find a chip i could use for the frequencies i mentioned and where to find it, i will be greatful
and am open for any suggestions to make this design better, or at least make it work :rolleyes:

thanks
