DESIGN AND MODELLING HILBERT TRANSFORM BASED PHASE DETECTOR FOR ALL DIGITAL PHASE LOCKED LOOP
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 5
Abstract
The Phase Locked Loop (PLL) is an almost always used electronics circuit for communication systems like modulator, demodulator, frequency generator and frequency synthesizer etc. All-digital phase locked loop (ADPLL) is digital version of the PLL. In this paper, a novel Hilbert transform based phase detection system for all-digital phase locked loop (ADPLL) is presented. The digital discrete time components are used to realize the phase detector system reducing the complexity of the design. The Hilbert transform based phase detection system provides a definite advantage over conventional analog phase detectors with both sinusoidal and its Quadrature signal. The studied system is modelled and tested in the MATLAB/Simulink environment.
