PLL Freq Det
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
- 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
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.
