发明名称 Electronic pulse counter for simultaneous downward and upward counting
摘要 An electronic pulse counter includes a given number of shift registers each having a different number of memory elements, an input, an output and a clocking line. Each of the shift registers is countercoupled by a negation between the input and the output thereof. A pulse counter input is formed by interconnection of the clocking lines of all of the shift registers. Pulse counter outputs are formed by the outputs of the shift registers.
