4 Bit Up Counter Circuit Diagram. To apply knowledge of the fundamental gates to create truth tables. 4 bit synchronous up counter.
Are enabled whereas the and gates 1 and 3 are disabled. 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. A 4 bit synchronous up counter start to count from 0 0000 in binary and increment or count upwards to 15 1111 in binary and then start new counting cycle by getting reset.
Below the circuit diagram and timing diagram are given along with the truth table.
To develop digital circuit building and troubleshooting skills. Are enabled whereas the and gates 1 and 3 are disabled. Below the circuit diagram and timing diagram are given along with the truth table. Its operating frequency is much higher than the same range asynchronous counter.
