Re: FSK modulator/demodulator



Did you have a look at a DDS such as the AD9833 ?
It is to expencive

They need to be at least the baudrate apart. Better a bit more.
I thought so. So they need to be a least about 300kHz apart (min.
200kbps)

A stability of 0.1% is not doable with pure analog
It doesn't need to be all analog
