## What is the characteristic equation of a JK flip-flop?

The characteristic equation of J-K flip-flop is given by: Q(n+1)=JQ'(n)+K’Q(n). Explanation: In J-K flip-flop, if both the inputs are same then it behaves like T flip-flop. Explanation: T flip-flop allows the same inputs. So, in J-K flip-flop J=K then it will work as T flip-flop.

## What are the characteristics of flip-flops?

A flip-flop is a device which stores a single bit (binary digit) of data; one of its two states represents a “one” and the other represents a “zero”. Such data storage can be used for storage of state, and such a circuit is described as sequential logic in electronics.

## What is SR in flip-flop?

This simple flip-flop is basically a one-bit memory bistable device that has two inputs, one which will “SET” the device (meaning the output = “1”), and is labelled S and one which will “RESET” the device (meaning the output = “0”), labelled R. Then the SR description stands for “Set-Reset”.

## What is the main characteristic of D flip flop?

The D type flip-flop has one data input ‘D’ and a clock input. The circuit edge triggers on. the clock input. The flip-flop also has two outputs Q and Q’ (where Q’ is the reverse of Q).

## What is basic flip flop?

A flip flop is an electronic circuit with two stable states that can be used to store binary data. The stored data can be changed by applying varying inputs. Both are used as data storage elements. It is the basic storage element in sequential logic.

## How are the characteristics of SR flip flop determined?

Characteristics table for SR Nand flip-flop Characteristics table is determined by the truth table of any circuit, it basically takes Q n, S and R as its inputs and Q n+1 as output. Q n+1 represents the next state while Q n represents the present state. While dealing with the characteristics table, the clock is high for all cases i.e CLK=1.

## Which is the characteristic equation of the JK flip flop?

The characteristic equation of the JK flip-flop is: Q next = J Q ¯ + K ¯ Q {\\displaystyle Q_{\ext{next}}=J{\\overline {Q}}+{\\overline {K}}Q} and the corresponding truth table is:

## How is JK flip flop similar to SR flip flop?

The operation of JK flip-flop is similar to SR flip-flop. Here, we considered the inputs of SR flip-flop as S = J Qt’ and R = KQt in order to utilize the modified SR flip-flop for 4 combinations of inputs. The following table shows the state table of JK flip-flop.

## What is the excitation table of flip flop?

The excitation table of any flip flop is drawn using its truth table. What is excitation table? For a given combination of present state Q n and next state Q n+1, excitation table tell the inputs required. Get more notes and other study material of Digital Design.
