SUMMARY

The discussion centers on amplitude modulation (AM) of a sinusoidal carrier wave with a frequency of 750kHz and an unmodulated amplitude of 4.0V, using a modulating signal of frequency 3kHz and amplitude 0.5V. The modulated carrier wave produces sidebands at frequencies of 750kHz ± 3kHz, resulting in frequency components at 747kHz and 753kHz. Understanding the time and frequency domain representations of the modulated signal is crucial for grasping the concept of AM.

PREREQUISITES
  • Basic understanding of sinusoidal waveforms
  • Knowledge of frequency modulation concepts
  • Familiarity with amplitude modulation principles

Hi everyone, plx help me on this!

I've worked out frequency modulation but can't understand amplitude modulation ...

A sinusoidal carrier wave has a frequency of 750kHz and an unmodulated amplitude of 4.0V. The carrier wave is to be amplitude-modulated by a sinusoidal signal of frequency 3kHz and the amplitude 0.5V. Describe the modulated carrier wave.


Thnx in advance :)
