ABSTRACT:
A one-shot tuning system for microprocessor controlled tuning systems uses a table look-up (105) to provide an offset value in response to a deviation error in the intermediate frequency of the tuner. This offset value is loaded into the programmable frequency divider (101) of the tuner to complete the tuning process.
