Harmonic Distortion in Communication SignalsObjectives: Equipment Required: Multisim version 8.0, Computer or laptop Theory: Total Harmonic Distortion (THD):(i)Harmonics are integer multiples of the fundamental or input frequency.(ii)Harmonics of 60 Hz are 60Hz (fundamental), 120 Hz, 180 Hz, 300 Hz, 420 Hz…(iii)Total Harmonic Distortion (THD) is the ratio of square root of the sum of the squares of individual rms harmonic voltages to the rms value of the fundamental and is given byWhereTHD =...

Objective: To study modulation and demodulation of AM signals, using Tutor Sims. The demodulation will be done using a diode and LPF.

ECET 310 An AM signal has an unmodulated carrier voltage VC = 10VP, a load resistance of RL = 10, and a modulation index of m = 1. Determine: (a)PC and PSB (b)Total power in the AM signal Find the modulation index corresponding to the given trapezoidal pattern for the AM signal. You are tuned to an AM station at 1200 KHz. Write down the frequency components of the received AM signal. Draw an AM signal for the given conditions: An AM transmitter is transmitting at 1000 W. If the modulation index...
