Flip-flops are synchronous bistable devices. The term synchronous means the output changes state only when the clock input is triggered. That is‚ changes in the output occur in synchronization with the clock. Flip-flop is a kind of multivibrator. There are three types of multivibrators: 1. Monostable multivibrator (also called one-shot) has only one stable state. It produces a single pulse in response to a triggering input. 2. Bistable multivibrator exhibits two stable states. It is

Introduction - Basic Flip-Flop Circuit A flip-flop circuit can be constructed from two NAND gates or two NOR gates. These flip-flops are shown in Figure 2 and Figure 3. Each flip-flop has two outputs‚ Q and Q’‚ and two inputs‚ set and reset. This type of flip-flop is referred to as an SR flip-flop or SR latch. The flip-flop in Figure 2 has two useful states. When Q=1 and Q’=0‚ it is in the set state (or 1-state). When Q=0 and Q’=1‚ it is in the clear state (or 0-state). The outputs Q and Q’ are

sequence of inputs‚ outputs‚ and internal states. There are two types of sequential circuits. Their classification depends on the timing of their signals: * Synchronous sequential circuits - This type of system uses storage elements called flip-flops that are employed to change their binary value only at discrete instants of time. Sequential circuits have a clock signal as one of their inputs. All state transitions in such circuits occur only when the clock value is either 0 or 1 or happen at

The government can help the economy in different ways. These methods include increasing or decreasing government spending or raising or cutting taxes. Increasing or decreasing government spending can have a flip-flop effect. On one hand‚ increasing government spending on programs like Social Security and Medicare are beneficial to Americans. However‚ if the government spends more on some programs and not on others‚ then things might become strenuous and make the economic impact more severe. For example
