Abstract
An FSK detector circuit and method which may be utilized for the demodulation of a digital data signal from a modulated sine wave carrier signal. A simple, low parts count FSK detector is disclosed which is readily implemented as an integrated circuit for the detection of a digital data signal in wireless applications without the use of an associated phase locked loop or other frequency detection circuitry.
