Abstract
A frequency-shift-keyed binary data signal demodulator utilizes a reference frequency equal to the arithmetic mean of the two tone frequencies corresponding to the two binary states of an FSK data signal. The frequency-acceptance bands of the FSK signals are varied by variation of the reference frequency. An auxiliary 'data valid' signal can be recovered along with the recovered binary data. A demodulator is also disclosed for providing maximum likelihood of detection of an FSK signal having a frequency shift which is a multiple of the bit rate.
