Abstract
A cellular phone terminal can eliminate extra process and save power to be consumed. The cellular phone terminal includes a low speed clock circuit generating a low speed clock to be used for generating a low speed clock used for generation of a preliminarily set intermittent reception cycle, and a high speed clock circuit generating a high speed clock required at least for receiving operation and stopped during periods other than a period of receiving operation, and performing at least checking of incoming call and measurement of a reception level according to said intermittent reception cycle. The terminal also includes an analog/digital converting circuit for converting a measured value of conditional variation in own terminal into the digital signal, an averaging circuit for averaging a result of measurement using said analog/digital converting circuit, and a control circuit for controlling said analog/digital converting circuit and said averaging circuit adapting to said intermittent reception cycle.
