California State Polytechnic University, Pomona Department of Electrical and Computer Engineering ECE 405L Electronic Communications Laboratory Experiment #3 Properties of Amplitude Modulation Waveforms Objective: To investigate the mathematical properties of Amplitude Modulation waveforms using common communications laboratory equipment. Pre-lab:1) Calculate the Fourier Spectrum for an amplitude modulated waveform having a carrier of 1 MHz, modulation of 10 KHz, and modulation percentage of: a) 50% b) 100% Set the amplitude of the carrier at 1 volt peak. 2) Calculate the Fourier Spectrum for an amplitude modulated waveform having a carrier of 1 MHz,

Lab: Using the equipment in the laboratory or bring the necessary electronic parts, construct the amplitude modulates waveforms described in the pre-lab then measure and record the Fourier Spectrums, the continuous and discrete forms. Make plots of the time and frequency domains for each waveform. Prove the Nyquist Criteria by showing a plot in the frequency domain. Post-Lab: In your report explain the differences between your calculated and your measured values....
