发明名称 BATTERY SAVING SIGNAL GENERATING CIRCUIT
摘要 <p>A battery saving signal generating circuit for saving energy of a battery assembled in a paging receiver. The signal generating circuit comprises a first circuit including a frequency divider operative to produce a first timing signal for determination of a time duration of each time slot pulse, a second circuit including a frequency divider operable independent of the first circuit to produce a second timing signals for determination of an occurrence interval of each time slot pulse. The signal generating circuit further comprises a third circuit responsive to the first and second timing signals to produce a time slot pulse signal. With this signal generating circuit, it is possible to independently and desirably select a time duration TW of the BSS time slot and a timing interval TD of the time slot occurrence, resulting in improvement in adaptability to paging receivers where different preamble signal lengths are required.</p>
