PLL Frequency Detector

Implements a PLL which locks to the input frequency and outputs an estimate of that frequency. Useful for FM Demod.

This PLL locks onto a [possibly noisy] reference carrier on the input and outputs an estimate of that frequency in radians per sample

Parameters
(R): Run-time adjustable


 * Loop bandwidth (R)
 * The loop bandwidth determines the lock range and should be set around pi/200 2pi/100.


 * Max freq
 * Maximum frequency of the carrier in radians per sample


 * Min freq
 * Minimum frequency of the carrier in radians per sample

Example Flowgraph


PLL Freq Det can be used to detect the frequency of a (noisy) single tone.

This minimal demo does nothing than allow the user to adjust a Signal Source's frequency, and then estimate the same.
