How to Retrieve the Carrier Frequency of Phase-Modulated or Carrier-Suppressed Signals with Costas Loops

on 08.11.2020 at 13:43 by Mehdi on Blog of Mehdi Alem
Introduction  Phase-locked loops (PLLs) are widely used to recover the frequency of a carrier signal in many detection systems such as lock-in amplifiers and data receivers. In order to properly lock to the carrier phase and extract its frequency, a […]

Enhancing the Luminosity Quality of Sulfur Plasma Lamps by the HF2PLL Phase-Locked Loop
