Under the control of microprocessor, this product with an oscillating implement embedded in can produce mulriple-scanning pulse electromagnetic wave with variable frequency and mulriple frequency conversion ultrasonic. Electromagnetic wave can get rid of the pests around electrical wire and ultrasonic can dispel the pests in other areas of the room. The product sends out frequency conversion signal of ultrasonic to circumambience. Once touches objects, it reflects and permeates the room. The combining of the two waves has mulriple effects on the central nervous and hearing system of the pests such as rats, cockroachs, spiders and ants. As a result, the pests would be on the rack and agonizing or even have the symptom of swivet and twitch.

它由完全内置的震荡器，在微电脑的控制下可产生多重扫描变频脉冲电磁波和复合变频超声波，电磁波主要解决电源线周围害虫的问题，而超声波是要消除室内其余区域的害虫，它向周围发射的变频超声波信号，当它碰到物体会反射，从而能充满整个房间，这两种波迭加在一起所产生的双重功效，对老鼠、蟑螂、蜘蛛、蚂蚁等害虫的中枢神经及听觉系统进行多重干扰，令其感到极度不适，恐慌不安，甚至表现出狂乱、抽搐等症状，并能使其丧失繁殖能力，迫使其逃离原地，从而达到驱赶害虫的目的。

We use this pulse as the control of counter. It means we take count of clock pulse during the phase difference pulse and get the phase difference later.

再由鉴相方波来控制计数器的开停，即用高频脉冲去填充两个信号的相位差，从而实现相位差的测量。
