Synchronous Up Down Counter Circuit Diagram. Synchronous up counter counts the number of clock pulses at its input from minimum to maximum. Q0 ties on each clk pulse for both up down series.
Whereas for the up down counter you can use multiplexers as switches as we saw in the design of the 3 bit synchronous up down counter. Synchronous binary up counter. Synchronous binary down counter.
The 3 bit synchronous binary up counter contains three t flip flops one 2 input and gate.
The circuit of the 3 bit synchronous up counter is shown below. If the up down control line is set to low then the bottom and gates are in enable state and the circuit acts as down counter. Synchronous up counter counts the number of clock pulses at its input from minimum to maximum. Synchronous up down counters circuit diagram.
