Device for the electro-optical display of the tuning of a television and/or sound radio receiver |
摘要 |
A device for the electro-optical display of the tuning of an electromagnetic wave receiver, such as a television or a radio, wherein the frequency of a received electromagnetic signal is measured and converted into a digital representation, which is applied to the input of a memory as the address of the various preprogrammed names of selected transmitting stations. The output of the memory is applied to select appropriate display elements of an electro-optical display and the selected display elements are then excited to provide a display indicative of the name or call letters of the transmitter station corresponding to the tuned receiver signal.
