Abstract:
1. A receiver comprising: a memory coupled to an edge detector and a counter, the edge detector configured to transfer a value from the counter to the memory whenever the edge detector detects an edge in an incoming signal; a controller configured to cause a switching element to select a modulated signal when the receiver is in a carrier frequency detection mode, the controller further configured to set an adjustable clock to a sampling rate for sampling a carrier signal, the controller further configured to determine a carrier frequency of the modulated signal after a predetermined condition is met while in the carrier frequency detection mode, the controller further configured to cause the switching element to select a demodulated signal and set the adjustable clock to a sampling rate for sampling the demodulated signal when the receiver is in a decoding mode and the controller further configured to add a total elapsed time to a first entry in the memory during a transition between carrier frequency detection mode and decoding mode.
