Synchronous Counter and the 4-bit Synchronous CounterBasic A 4-bit decade synchronous counter can also be built using synchronous binary counters to produce a count sequence from 0 to 9. A standard binary counter can be converted to a decade (decimal 10) counter with the aid of some additional logic to implement the desired state sequence.2. Asynchronous Counter · Bidirectional Counter Circuit Design of a 4-bit Binary Counter Using D Flip Nov 05, 2015Design a circuit for an edge triggered 4-bit binary up counter (0000 to 1111). When it reaches “1111”, it should revert back to “0000” after the next edge. Use positive edge triggered D flip-flop (shown in the below figure) to design the circuit.
