The Digital Communication Modulation and Detection Board is a comprehensive instructional module that plugs directly into the Electronics Universal Training System base unit designed to teach the fundamental concepts of various digital modulation and demodulation techniques as well as their related circuits to students who are both beginners and experts alike. The topics covered on this board include: transmitting and receiving digital signals, bandpass filters, amplitude shift keying (ASK), frequency shift keying (FSK), binary phase shift keying (BPSK), differential phase shift keying (DPSK), quadrature phase shift keying (QPSK), signature follower with a PLL, and troubleshooting exercises. A minimal amount of wiring is required to setup the board, increasing the amount of time students have for hands on learning. The fault insertion system allows you to create an error on the board for students to troubleshoot, further developing their diagnostic skills. By creating, testing, and performing experiments from the included manual, students will learn the theory, practical applications, and gain a working knowledge of the fundamental concepts of digital communication, modulation, and detection.
