Set of FM demodulators
Original language description
The set of three demodulator boards for demodulating a frequency modulated (FM or FSK) signal into a baseband signal has been designed and constructed. The demodulators include detectors arrangements following the Travis detector, PLL based detector, andcoincidence FM detector, all with roughly the same bandwidth and operation frequency. The demodulators were evaluated and compared from the linearity performance point of view and the signal-to-noise ratio (SNR) performance point of view. Moreover, thenoise threshold of all three detectors was studied within the AWGN and non-AWGN noisy channels. The comparison between the theoretical assumptions/simulations and measurement results was made. The results show slight discrepancy between assumptions and real demodulators' performance for SNR close to noise threshold. All measured results hints the demodulators' suitability for different reception scenario of FM and FSK carriers.
