Phase-Locked loop and Amplitude-Locked Loop Simulation
The program simulates an analogue PLL. It demodulates an FM waveform. You can vary the baseband frequency. It uses an amplitude-locked loop (ALL) instead of a hard limiter. More details on the ALL can be found at Ampsys Electronics,Paisley,Scotland.
