This project was done in collaboration with my teammates in EGR334 at ASU. Introduction Many analog-digital converters work by having a successive approximation register (SAR) digitally approximate (guess) a voltage, and having an op- amp comparator compare the guessed voltage to the analog input. The output of the comparator […]

FM Demodulation using a Phase-Locked Loop (PLL)
Phase-Locked Loops (PLLs) are widely used in technologies that require motor speed controls, tracking filters, frequency synthesis providing multiple of a reference signal frequency, and frequency shift keying or FSK that decodes for demodulation carrier frequencies. For our project, we will be using a phase-locked loop to demodulate an existing […]
