#175011 - Incomplete question
Responding to: ???'s previous message
Is there a reason why you think the 89S51 would not be able to?

Some important information you did not supply:
- what frequencies of the FSK signal?
- how many periods of constant frequency in a bit?
- digital or analog processing of the input signal?
- should the 89S51 measure the periods of the signal, or should you use external hardware?
