Digital Communications 1 (91022)

The Digital Communications 1 Circuit Board includes the following five circuit blocks.

  • Pulse Amplitude Modulation (PAM)
  • Pulse-Time Modulation (PTM)
  • Pulse-Code Modulation (PCM)
  • Pulse Amplitude Modulation Time-Division Multiplexing (PAM-TDM)
  • Delta Modulation (DM)

 

In addition, the circuit board contains the following features:

  • Each circuit block contains a modulator for transmission and a demodulator for reception.
  • Built-in Channel Simulator and Speaker Amp Circuitry
  • The Channel Simulator circuit block enables the student to investigate the effects of noise and channel bandwidth on pulse and digital modulation signals.
  • The Speaker Amp circuit block permits the student to connect a speaker and listen to the signals.
  • Communication signals are synchronized for easy display.
