MULTIPLEXING ARRANGEMENT FOR A TELEVISION SIGNAL PROCESSING SYSTEM |
摘要 |
A channel number display arrangement for a television receiver includes a multiplexer for alternately coupling binary signals representing the tens and units digits of the channel number of a selected channel to a single decoder and driver arrangement. To reduce visible effects of switching transients, the switching operation of the multiplexer is synchronized with respect to the receiver's deflection signals so that switching transients occur during horizontal retrace intervals in which the receiver's electron beams are normally blanked. In addition, keyed AGC circuitry, normally activated during the horizontal retrace intervals, is inhibited during the switching operation so that it is not erroneously set up in response to switching transients. |
