11. Counters and Registers - Part B
Synchronous counters operate by clocking all flip-flops simultaneously, reducing propagation delay compared to asynchronous counters. Various types include UP/DOWN counters, decade counters, BCD counters, and presettable counters, each with unique functionalities. These concepts enable efficient counting mechanisms essential in digital electronics design.

What we have learnt
- Synchronous counters clock all flip-flops at the same time, offering lower propagation delays.
- UP/DOWN counters can count forward and backward, while decade counters reset after ten counts.
- Presettable counters allow setting a specific starting count, enhancing flexibility in counting applications.
Key Concepts
- -- Synchronous Counter
- A counter where all flip-flops are clocked simultaneously, reducing propagation delay.
- -- UP/DOWN Counter
- A counter that can be configured to count upwards or downwards based on a control input.
- -- Decade Counter
- A MOD-10 counter that counts through ten unique states before resetting.
- -- BCD Counter
- A counter that counts from 0000 to 1001, representing decimal numbers 0 to 9.
- -- Presettable Counter
- A counter that can be set to an initial value either asynchronously or synchronously.
