摘要
Depending on the received standard, certain stages (2-5) must be switched on or off. The object consists in creating a particularly simple and universally applicable control circuit for the stages. The stages are controlled by means of a tri-state decoder (9) which is controlled by a standard generator (8). Particularly suitable for an adapter module for multi-standard operation in a colour-television receiver. IMAGE
