Logic controlled tuning signal level and deviation compensation in a radio telephone

摘要

Radio telephone tuning information is determined by a measuring computer (20) stored in the memory of the radio telephone (1). A microprocessor (10) receives from the sensors (14) information about the operating temperature, according to which appropriate tuning data is selected from memory. The information is used to adjust signal levels and deviations through logic controlled amplifiers (16, 17). The tuning can be made automatically without opening the casing of the radio telephone.
