PhaseLockedLoop
- %The phase locked loop(PLL),adjusts the phase of a local oscillator %w.r.t the incoming modulated signal.In this way,the phase of the %incoming signal is locked and the signal is demodulated.This scheme %is used in PM and FM as well. %We wi

adfmreceiver
- The design of the All Digital FM Receiver circuit in this project uses Phase Locked Loop (PLL) as the main core. The task of the PLL is to maintain coherence between the input (modulated) signal frequency,iωand the respective output frequency,oωvia p
