Why use an FM system in the classroom?

What are the disadvantages of FM system?

Disadvantages of FM: Much more Bandwidth (as much as 20 times as much). Frequency Modulation

  • Improved signal to noise ratio (about 25dB) w.r.t. to man made interference.
  • Smaller geographical interference between neighboring stations.
  • Less radiated power.
  • Well defined service areas for given transmitter power.

How does an FM work?
