EMPLOYING DIGITAL SIMULATION TECHNIQUES

ments for the degree of Master of Science. The optimum phase-locked loop demodulator arises in a natural way from statistical detection theory when the received signal is an angle-modulated cosine function that is corrupted by additive independent white Gaussian noise. In particular, for a frequency-modulated signal the phase-locked loop can be revamped into a non-linear feedback system with the integrated message as an input. The object of the thesis is to analyze the performance of the above explained non-linear system. The primary means of analysis is with the use of digital simulation techniques. Secondary methods include a quasi-linear analysis and a linear analysis. Only the simulation analysis provides com-plete coverage of the system performance for all input sig
