Amplitude Modulation and Demodulation

The instrument is designed to demonstrate the method to transmit signals via. Electromagnetic transmission. It is still used in radio systems to transmit audio signals although it has lesser in popularity compared to FM (Frequency Modulation) due to its lower signal-to-noise ratio.

Technical Specification:-

  • IC-based DC regulated power supply ±12 V / 500 mA.
  • Audio frequency 1 KHz / 0-2 Vpp for modulating signal 455 KHz / 2.5 Vpp approx. for Carrier Frequency.
