ABSTRACT:
An FSK receiver for a single channel analog telemetry system comprises an FSK demodulator, a frequency multiplier, and a frequency-to-voltage converter. An FSK transmitter comprises a voltage-to-frequency converter, a frequency divider, and an FSK tone generator. The principal advantages of this system are greater speed due to faster settling time and reduced errors in accuracy and linearity.
