- 2. Introduction to Flip-Flops Flip-flops are devices used in the digital field for a variety of purposes. When properly connected, flip-flops may be used to store data temporarily, to multiply or divide, to count operations, or to receive and transfer information.
- 3. Flip Flop Triggering ● When the flip-flop is triggered to update its output state on the rising or falling edge of the clock pulse, then it is called edge triggering method. ● If the flip-flop is triggered when the clock pulse goes from low to high (positive edge), then it is called positive edge-triggering method.
- 4. Types of Flip Flop ● Latch or Set-Reset (SR) flip-flop. ● JK flip-flop. ● T (Toggle) flip-flop. ● D (Delay or Data) flip-flop.

- 9. Asynchronous vs Synchronous Triggering ● All flip flips in a synchronous counter are triggered simultaneously by the same clock. ● Various flip-flops are activated with different clocks rather than simultaneously in an asynchronous counter. ● Asynchronous counters operate more slowly than synchronized counters.
- 10. Synchronous Triggering ● Synchronous triggers must complete before further operations can continue. ● They are typically run when the event is initiated but before it finishes. ● The event completion is dependent on their success. Triggers are run synchronously by default.
- 11. Asynchronous Triggering ● Asynchronous trigger is a change event trigger which run asynchronously after a database transaction is completed. ● The async execution of change event trigger makes them ideal for processing resource-intensive business logic in separate transaction from database transaction.
- 12. Edge-Triggered vs. Level-Triggered Flip-Flops ● Edge triggering is frequently used in synchronous circuits, such as counters and flip-flops. ● Level triggering is frequently employed in applications that call for continuous monitoring of an input signal, such as data acquisition and control systems.
- 13. Positive Edge-Triggered vs Negative Edge- Triggered Flip-Flops ● Positive edge triggering is indicated by a triangle at the clock terminal of the flip-flop. ● Negative edge triggering is indicated by a triangle with a bubble at the clock terminal of the flip-flop. Different types of edge triggered flip-flop include edge-triggered S-R flip-flop, D flip-flop and J-K flip- flop.
