<p>SO1098 TUNER WITH PRESETTABLE CHANNEL SELECTION Improvements in signal receiving apparatus of the type including a tuning stage having a presettable channel selecting storage device for storing selected channel identity signals representing predetermined channels to which the tuning stage is tunable and wherein any of the stored channel identity signals is selectively read out so as to control the tuning stage to be tuned to the channel represented by the read out channel identity signal. The improvements comprise a presettable memory device for storing control signals associated with the respective predetermined channels, these control signals being used to control at least one operating condition of the signal receiving apparatus. A selectively operable preset circuit generates at least one control signal for storage in the memory device when the tuning stage is tuned to an associated channel during a preset operation. A particular stored channel identity signal is read out from the storage device and, concurrently therewith, at least one control signal associated with the channel represented by the read out channel identity signal is read out of the memory device. The read out channel identity signal determines the channel to which the tuning stage is tuned, and the read out control signal, or signals, determines the operating condition of the signal receiving apparatus for that channel. -i-</p> |
