Television
The television receiver can also be defined as the television set most people have in their homes. It normally receives a transmitted signal via an aerial cable and converts this radio frequency (RF) signal (or more precisely UHF signal) into picture plus colour and sound. Most microcomputer have sockets which gives a signal suitable for displaying the output on a television receiver but it is necessary to ‘tune’ the television to the required channel the first time this is done. Some sets are receiver/monitor and these have a second input socket, which accepts a video signal from a microcomputer. This provides a better quality picture particularly when displaying detailed graphics. For the clearest quality colour picture the red, green and blue signals are sent separately and this requires an RGB computer output and an RGB monitor.
