What to Focus On

  • Transmitter, channel, and receiver are essential components.
  • Antenna size must be comparable to the signal wavelength (≥ λ/4).
  • Noise, attenuation, sensitivity, selectivity, and fidelity affect communication quality.
  • Analog signals are continuous; digital signals are discrete (binary).
  • Bandwidth determines information-carrying capacity.
  • Sampling theorem ensures no loss of information during analog-to-digital conversion.
  • Modulation enables long-distance transmission of low-frequency signals.
  • AM varies amplitude; FM varies frequency of the carrier wave.
  • FM offers higher fidelity and noise resistance compared to AM.

Common Mistakes to Avoid

Low-frequency signals can be transmitted directly over long distances using small antennas.

AM and FM signals differ only in sound quality, not in how they carry information.

Digital signals are always better than analog signals in every way.
