K 22


  • To study the Amplitude Shift Keying Modulation and Demodulation.

Features of the Trainer:

Clock Generator:

  • Output Wave form : Square
  • Frequency : 100KHZ 
  • Amplitude : 10V (P-P)

Audio Oscillator:

  • Output Wave form : Sine
  • Amplitude :0-10V (P-P)
  • Frequency :200Hz-2KHz

Gain Control:

  • This pot adjusts the amplification of the modulator’s output.

Modulation Offset:

  • This control is used to adjust the amplitude of the OFF signal. Adjust this control till the amplitude of the OFF signal is close to zero as possible. Carrier Offset:
  • This control adjusts the off bias level of the ASK waveform. Adjust this control till the off level occurs midway between the ON signal peaks.)
