Synchronous Counters offer speed advantages over Asynchronous Counters while Asynchronous Counters are simpler in design and consume less power. To upgrade a 3-Bit counter to a 4-Bit counter, an extra flip-flop needs to be added.
Synchronous Counters have advantages over Asynchronous Counters in terms of speed, as they operate based on a clock signal, ensuring all flip-flops change simultaneously, allowing for faster counting. Additionally, synchronous counters are easier to design and analyze compared to asynchronous counters, which are more complex due to the ripple effect. On the other hand, Asynchronous Counters have the advantage of simplicity in design and lower power consumption compared to synchronous counters.
To change a 3-bit counter to a 4-bit counter, an additional flip-flop needs to be added to the circuit. This extra flip-flop will increase the counting range from 2^3 to 2^4, allowing the counter to count up to 16 different states instead of 8.
