Model: K12


K12 1



  • This training board consists of the main pulse coder & decoder. The frequency and amplitude of the required clock generator, pulse generator and the audio generator can be adjusted. In PCM the message signal is sampled and the amplitude of each sample is rounded off to the nearest one of a finite set of allowable values, so that both time and amplitude are in discrete form. This allows the message to be transmitted by means of coded electrical signals. Thus, the study of PCM & demodulation is necessary in order to understand Communication system; Lab PCM trainer consists of Built in.
  • To construct and study Pulse Code Modulator and observe its waveform.
  • To observe the pulse decoded waveform." change audio generator frequency upto 2KHz
