91023-2

Description

The Digital Communications 2 module enables students to configure, operate, and troubleshoot the following circuits:

• NRZ, RZ, and Manchester Encoding and Decoding

• Clock Synchronizer

• Frequency-Shift Keying (FSK) Generation

• FSK Asynchronous and Synchronous Detection

• Phase-Shift Keying (PSK) Generation

• PSK Asynchronous and Synchronous Detection

• Amplitude-Shift Keying (ASK) Generation

• ASK Asynchronous and Synchronous Detection

• Channel Effects

• FSK Modem

The circuits found on this board include:

• Line Encoding

• Modulators

• Channel Simulator

• Sync Detector

• Modem

This board is available in the following language variants:

• English variant: 91023-20

• French variant: 91023-21

• Spanish variant: 91023-22

Features & Benefits

  • The Channel Simulator circuit block and a bit error rate (BER) counter enable students to evaluate the effects of noise on ASK and PSK modulated carrier signals.
  • The Modem circuit block contains an FSK/DPSK modem IC, which students use in a loop-back mode to observe the entire signal path.
  • Communication signals are synchronized for easy display.
