摘要： Method for automatically controlling the optimal tuning point for receiving teletext increases or decreases the tuning point by steps of a certain frequency for the byte error at each step tuning point to be detected and memorized so that the tuning point for the minimal byte error is found to provide the optimal tuning frequency for receiving a teletext, thus eliminating the inconvenience of manipulating a key to find the optimal tuning point from the display on a TV screen. The system of the method employs a microprocessor and a teletext processor in addition to the tuner.

摘要： Television systems comprising tuners (1), controllers (2) for controlling tuners (1), and stages (3) for receiving tuned signals from tuners (1) and for supplying control signals to controllers (2), use time-consuming automatic fine tuning signals while high speed tuning. By using lock signals (53) from phase-locked-loops (31) in stages (3) as control signals, an indication whether a channel is active or not can now be got much quicker due to lock signals being much faster available than automatic fine tuning signals. By using synchronization signals (54) from synchronization generators (4) as further control signals, a further indication is got. In a fast tuning mode, frequencies nearby active channels are detected, and in a fine tuning mode, channel frequencies are identified. According to the basic idea, lock signals originating from phase-locked-loops (31) in stages (3) can give first indications whether a channel is active or not, preferably and further advantageously in combination with second indications based upon synchronization signals (54).

摘要： In a mobile communication terminal, a switch 10 is initially set to an initial setting mode at time of turning on a power supply. A reference oscillator control circuit is initialized, and in this state, the output frequency of a reference oscillator is usually greatly shifted. The base station search is first conducted, and as a result, if the base station cannot be grasped, an offset signal is generated by a frequency offset generating circuit 12, to shift the output frequency of a reference oscillator 6 through a reference oscillator control circuit 5. This operation is repeated until the base station is grasped so that the base station search is continued while the output frequency of the reference oscillator 6 is being shifted. When a grasp of the base station succeeds, the switch 10 is switched to an AFC side to conduct automatic frequency adjustment.
