Published:2011/8/18 3:49:00 Author: | Keyword: multi-function, electric stimulation, therapeutic apparatus | From:SeekIC

IC1 generates the clock pulse of 256Hz, and its output is added on the 1-pin of IC2. IC2(CD4024) is a binary pulse counter/frequency distributor, whose output frequency is 128~2Hz. The pulse signal output by IC2 is sent to the 1-pin of IC3(CD4024), the output terminals of 4, 5 and 6 generate the pulses of 8s, 16s and 32s respectively, which are to control the 8-bit electric switch in IC4(CD4051) and make the switch conducted every 8s in sequence. The output of IC1 and IC2 are linked to one terminal of IC4 8-bit e-switch.
