Class Information
Number: 377
Name: Electrical pulse counters, pulse dividers, or shift registers: circuits and systems >
Description: This is the generic class for circuits or devices for making a count of electrical pulses; for circuits or devices for producing output pulses which are a fraction of the number of input pulses i.e., pulse dividers of for devices where information is stored in and serially transferred through a storage medium i.e., shift registers. Also included are pulse multipliers which make use of pulse dividing circuits.
