Abstract: Elearning involves the proper use of the models, method, tasks, the material base and the problems in the teaching process using the digital phase locked loop. We have studied the many types of phase and phase frequency detectors. Their parameters are assessed and the features of different applications are discussed. We in this work developed and tested Different types of digital integrators and digital filters along with the different phase-frequency detectors. Besides we experimented the circuits for Digitally Controlled Oscillators. Also many varied phase locked loops are built and tested. Then finally we have described the parameters used.
Keywords: All Digital Phase Locked Loop, Teaching methodology, Phase-frequency detector, Digitally Controlled Oscillator, FPGA Models, Methods and Material Base of the Elearning Process
