Abstract
A signal seeking tuning system includes provisions for allowing the direct selection of channels. It includes a memory for storing lower and upper boundaries of a tuning control voltage range for each channel which may be selected. When a channel is selected, a microcomputer causes the memory location corresponding to one of the boundaries associated with the selected channel to be addressed and causes a tuning voltage generator to change the magnitude of the tuning control voltage in the direction of the boundary. A comparator determines when the tuning control voltage reaches the boundary. Thereafter, the microcomputer controls a signal seeking operation between the boundaries to tune the RF carrier associated with the selected channel.
