What is FM Modulator and Demodulator Lab Report about?

This lab investigates frequency modulation (FM) using a phase-locked loop (PLL) integrated circuit. Students will build an FM modulator and demodulator using an MC14046 PLL chip. The goal is to generate an FM signal from a carrier and message signal, and then recover the original message through demodulation. Students are asked to adjust the circuits, observe the waveforms, and analyze the signal spectra for different modulation indices. They will also estimate the number of sidebands and bandwidth needed t
