Abstract
The purpose of this chapter is to introduce a complete TV receiver in a block diagram form. The reader will be able to see at a glance how the composite signal is processed before the individual outputs are obtained. A colour receiver has a number of features which are common to its monochrome counterpart. The practical circuits of the two types may differ in detail because of the more stringent requirements of a colour set, but the basic principles are similar. The block diagram approach is most helpful when one is dealing with unfamiliar receivers, whose circuit diagrams can then be divided into their various functions. In modern designs a number of integrated circuits are used to replace the blocks in our diagram. Alternatively, the layout may be in the form of modules or panels which carry the components associated with essential functions so as to simplify initial fault-finding. In field servicing it is then a simple matter of replacing a faulty module with a new one, since efficient repairs may require either a high degree of skill or complex test equipment.
