A counter for inserting a deliberate time delay allowing an operation external to the program to occur.
作为延迟装置的计数器,延迟时间内允许执行一个程序以外的操作。
The counter includes an inverter and cascading delay stages having selectable stage delays.
该计数器包括倒相器和具有可选择级延迟的级联延迟级。
Anoiher signal with 90 degree delay is obtained by phase shift circuit. The accurate and stable circle counting is done by a reversible counter.
通过移相电路获得相差90度的另一路信号,然后用可逆计数器实现稳定准确的周期计数。
