FREQUENCY MODULATION (FM) TRAINER

THE FREQUENCY MODULATION (FM)  AND DEMODULATION RADIO TRAINER  is a comprehensive learning solution specifically designed to study the basic operations of frequency modulation and demodulation techniques and systems. It also provides a conceptual and step-by-step understanding through observation of waveforms at various test points. Blockwise modular organization of circuit function with supporting technical information makes it easy to understand the process of FM generation and detection. The exercises conceived to provide a practical approach to the subjects enable deep analysis of the subjects and will guide the students to understand each function.

THE FREQUENCY MODULATION (FM)  AND DEMODULATION TRAINER is an ideal teaching aid to enhance education, training, and skills development among our young minds.
