EC – Communication Systems Laboratory 7 Department of Electronics and Communication Engineering Varuvan Vadivelan Institute of Technology, Dharmapuri – Exp. No.: 3 Date: AMPLITUDE MODULATION AND DEMODULATON AIM: To perform the amplitude modulation and demodulation using AM Kit. PCS Lab Manual Page 5 THEORY: Amplitude modulation is one of the earliest radio modulation techniques. The receivers used to listen to AM-DSB-C are perhaps the simplest receivers of any radio modulation technique; which may be why that version of amplitude modulation is still widely used today. generating an AM signal with a depth of modulation exceeding %, and without any RF distortion whatsoever. But we are getting ahead of ourselves, as we have not yet even defined what AM is! theory The amplitude modulated signal is defined as: AM = E (1 + www.doorway.ruµt) cosωt .. 1 = A (1 + www.doorway.ruµt). B cosωt .. 2.

PCS Lab Manual Page 5 THEORY: Amplitude modulation is one of the earliest radio modulation techniques. The receivers used to listen to AM-DSB-C are perhaps the simplest receivers of any radio modulation technique; which may be why that version of amplitude modulation is still widely used today. In your lab write up compare this with what is expected for a modulation depth of m = 1. T12 Measure the peak-to-peak amplitude of the AM signal, with m = 1, and confirm that this magnitude is as predicted, knowing the signal levels into the MULTIPLIER, and its 'k' factor. The significance of 'm'. 5 Amplitude Modulation Summary This laboratory exercise has two objectives. The first is to gain experience in actually programming the USRP to act as a transmitter or a receiver. The second is to investigate classical analog amplitude modulation and the envelope detector.
