Introduction: LAB Colour TV Dynamic Demonstrator is a comprehensive trainer. In this trainer all importance has been given to practical study of various parameters. All these circuits are mounted on a single PCB. Hence all wiring mistakes are totally eliminated. Therefore the performance of all trainer will be greatly enhanced. NOTE: However performance of our TV trainer may vary in operation compared to commercial TV Receivers. You must make your own arrangements for erecting antenna at your college.
