#Scilab signal how to#

If we know that a symbol has one of two frequencies, we multiply the received signal by reference signals corresponding to the two frequencies, and the waveform resulting from this multiplication will have a relatively large DC offset if the frequency of the received symbol is similar to the frequency of the reference signal.

In the previous article on how to decode an FSK signal, we saw that multiplication can be used to identify the frequency of a given portion of a received waveform.
