Experiment #3 ECE 405L Objective: One objective of this lab is to investigate the mathematical properties of Amplitude Modulation/Demodulation waveforms using common communications laboratory equipment. Another objective of this lab is to learn how to use the laboratory equipment to modulate different signals using the Amplitude Modulation feature. Theories: In this lab we evaluated the following theories: Fourier Transfer Function Rectification Faraday’s Law Frequency Multiplication Pre-lab: The pre-lab calculations were calculated using the following am modulation equation: = + - - + st Asin2πfct AB2cos2πfc fmt AB2cos2πfc fmt The diode equation was also used which is the following: = - - +… st 12 2πsinωt 23πsin3ωt The pre-lab calculations are on the following page. Calibration:
