The Analog communications course provides comprehensive, hands-on instruction in the terminology, principles and applications of analog communications. In this course, students receive hands-on circuit training and acquire skills to measure radio signals with an oscilloscope. Students also learn the functions of oscillators, filters, amplifiers, LC networks, modulators, limiters, mixers, and Detectors in communication circuits. Lab Analog Communication Trainer is a very versatile and completely self-contained laboratory instrument built in regulated power supply with short circuit protection. This trainer consists of the following fundamental logic gates:
