Abstract :
In MFCW (multi-frequency continuous-wave) systems, sidetones are generally transmitted by angular modulation. A novel method named SLP (spectrum-line processing) for analyzing the phase shift of the demodulated sidetone of the distorted monotone FM signal after passing a linear system is presented firstly, and then generalized to nonlinear systems. Compared to the complicated traditional method, the effect of nonideal channel characteristics on the demodulated sidetone phase when frequency or power of the carrier varies can be effectively analyzed.
