40520 DSB/SSB AM Transmitter Trainer is a comprehensive learning solution specifically designed to study basic operation as well as to provide conceptual and step by step understanding of DSB/SSB Amplitude modulation and transmission system through measurement of voltages and observation of waveforms at various test points. Block wise modular organization of circuit function with supporting technical information makes it easy to understand the process of AM generation and transmission. The exercises conceived to provide a practical approach to the subjects enable a deep analysis of the subjects and will guide the students to understand each function.
