Televison Trainers Dynamic Demonstrators
BLACK AND WHITE TV DYNAMIC DEMONSTRATOR
Introduction:
Black and White TV Dynamic Demonstrator is a comprehensive trainer. In this trainer all importance has been given to understand the practical aspects of television receiver. All these circuits are mounted on a single PCB. Hence all wiring mistakes are totally eliminated. Therefore the performance of the trainer will be greatly enhanced. However performance of our TV trainer may vary in operation compared to commercial TV Receivers. You must make your own arrangement for erecting antenna at your place. Our Manual is very descriptive giving details to conduct experiments, like trouble shooting, identifying faulty sections by simulating faults through SPDT switches etc.,
