Abstract
A frequency shift keying (FSK) demodulation component having of a sampler that receives an FSK modulated signal, samples the received FSK modulated signal, and outputs the sampled signal. The FSK demodulation component further includes a low pass filter that filters the sampled signal, and a frequency shift detector that detects shifts in frequency of the low pass filtered sampled signal. The FSK demodulation component then outputs an indication of the detection of shifts in frequency of the low pass filtered sampled signal.
