PLL Carrier Regeneration
Jump to navigation
Jump to search
Implements a PLL which locks to the input frequency and outputs a carrier.
This PLL locks onto a [possibly noisy] reference carrier on the input and outputs a clean version which is phase and frequency aligned to it.
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
This flowgraph implements a Broadcast FM stereo receiver using basic blocks. The PLL captures the 19kHz pilot carrier.
