PLL Phase Detector

1. VPItransmissionMaker™ and VPIcomponentMaker™ include hundreds of signal processing modules for the manipulation of electrical and digital signals.
2. These can be used together with the photonic modules to investigate both the electronic and optical aspects of communications systems, such as signal recovery and improvement using electrical signal processing.
3. This example shows a simulation of a digital state-machine for the comparison of phases of two signals (a 'phase detector').
4. This circuit can be used to investigate the locking and acquisition of phase-locked loops, particularly for optical packet-switched systems where rapid clock recovery is critical.
