Modulus Counters, or simply MOD counters, are defined based on the number of states that the counter will sequence through before returning back to its original value. In other words, the modulus (or just modulo) is the number of states the counter counts and is the dividing number of the counter. The number of states or counting sequences through which a particular counter advances before returning once again back to its original first state is called the modulus (MOD). Then counters are sequential logic devices that follow a predetermined sequence of counting states which are triggered by an external clock (CLK) signal. Whereas an asynchronous counter circuit is independent of the input clock so the data bits change state at different times one after the other. With synchronous counters, all the data bits change synchronously with the application of a clock signal. A counter can be constructed to operate as a synchronous circuit or as an asynchronous circuit. Counters that operate in both the UP and DOWN modes, are called bidirectional counters.Ĭounters are sequential logic devices that are activated or triggered by an external timing pulse or clock signal. Likewise, counters which decrease their sequence of numbers or states when activated by a clock input are said to operate in a “count-down” mode. Counters which advance their sequence of numbers or states when activated by a clock input are said to operate in a “count-up” mode. The job of a counter is to count by advancing the contents of the counter by one count with each clock pulse.
