pll.rar
A Matlab script to simulate a Phase-Locked Loop (PLL). This is a type II PLL ie it has two integrators (one of these is the VCO itself).
It is simulated with an FM (frequency modulation) input. The output is the demodulated baseband signal

... 2) to reduce the presence of noise in it and then we can calculate:
• what limits the signal word out (segmentation)
• how are these words
• the characteristic frequency of the voice of the speaker of each file (voice pitch).
