Abstract :
The FM threshold performance of the frequency demodulator with feedback (FMFB) is experimentally optimized. Rules of thumb for the practical design of the FMFB with limiter in the loop are proposed. Such design rules provide for optimum FMFB threshold performance given specifications of the received signal. Equivalences among the FMFB, phase-locked loop, and limiter- discriminator offer some additional physical insight into the threshold-extending mechanism of the FMFB not presented by previous investigators.
