Ryan Beasley Experiment #5 ECE 405L Objective: One objective of this lab is to investigate the mathematical properties of Frequency Demodulation waveforms using common communications laboratory equipment. Another objective of this lab is to learn the properties of a Phase Locked Loop demodulator. Theories: In this lab we evaluated the following theories: Frequency Demodulation (FM) Phase Locked Loop (PLL) circuitry Pre-lab: Common mathematical principles were using in determining the pre-lab values, including the Fourier Transform. The pre-lab calculations are on the following pages. Calibration:
