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 reveiver. All these circuits
are mounted on a single PCB. Hence all wiring mistakes are totably 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.
