Simplified FSK Signal Detection
FSK (Frequency Shift Keying) is the modulation cornerstone of a number of digital data transmission systems. The transmit signal is relatively easy to generate. Receive processing is tolerant of a wide range of signals and relatively immune to a large class of interfering signals. This Application Note outlines a simple, almost-all hardware method for detecting FSK signals using the analog signal processing capabilities of the PSoC(R).
