MEMORY DEVICE FOR AUTOMATIC SWITCHING CONTROL SYSTEMS

摘要

A memory device for automatic switching control systems using pulse patterns for the switching control. The working pulse pattern and the test pulse pattern are fed to the input of a shift register which has one more register stage than the number of clock pulses per pulse pattern. The clock pulse signal and an erase signal pattern, which is present as required are also fed to the shift register. A logic circuit arrangement is connected to the shift register to detect the presence of a working pulse pattern therein and to cause same to be stored in the shift register.
