Abstract

In Amplitude Modulation (AM), the amplitude of the carrier changes in accordance with the input analog signal, while the frequency of the carrier remains the same. The modulated carrier contains several spectral components, requiring frequency domain analysis. In an effort to examine this, this chapter presents the following topics:
  • Amplitude Modulation (AM) and AM spectrum

  • Double sideband-suppressed carrier (DSBSC) and DSBSC spectrum

  • Single sideband (SSB) carrier and SSB spectrum

These materials have been augmented by diagrams and associated waveforms to make them easier for readers to grasp.
