#Rs edge triggered flip flop series

The above inverter-based flip-flop can be implemented using a NOR gate as shown below. This is where NOR and NAND Gates come into picture. The above inverter-based flip-flop is just for understanding the working but it doesnвЂ™t have any practical uses as there is no provision for applying any inputs. This is a simple flip-flop with two stable states and it remains in a particular state, hence a memory, until there is an external event (like change in input in this, case). Similarly, instead of ground, if we repeat the same process with 1 (Logic 1, HIGH, bit 1), the output Q 3 stays at 1. Now, if the feedback is connected and the input Q 1 is disconnected from ground, the Q 3 will still continue to be at 0. Initially, assume the feedback is disconnected and Q 1 is made 0 (Logic 0, LOW, bit 0) by connecting it to ground. Let Q 1 be the input and Q 3 be the output. The following circuits shows the flip-flop using inverters.

Since it retains the output long after the input is applied (unless something is done to change it), a Flip-Flop can be considered as Memory Device, which can store one binary bit.ДЄ simple flip-flop can be designed using two Inverters in series with a feedback from output of second inverter to the input of first inverter. As a flip-flop is a bistable element, its output remains in either of the stable states until an external event (known as a trigger) is applied. It is a Bistable Electronic Circuit i.e., it has two stable states: HIGH or LOW. What is a Flip-Flop?ДЄ Flip-Flop is a basic memory unit which can store 1-bit of digital information. To put the difference in simple terms, a flip-flop is a clock-controlled latch i.e., the output changes only when there is a clock signal (a HIGH or LOW level, depending on the design). NOTE: The terms вЂњlatchвЂќ and вЂњflip-flopвЂќ will be used synonymously, although technically they are slightly different. The devices or circuits which can store data and act as a вЂњmemoryвЂќ unit are known as Latches or Flip-Flops. How can we get the вЂњpast input / outputвЂќ data? We have to have some kind of вЂњmemoryвЂќ to be able to store the data for later use. These types of circuits are known as Sequential Logic Circuits. There are another class of circuits where the output not only depends on the present input, but also on the past inputs / outputs.

In these types of circuits, the output is dependent only on the current state of the input and it doesnвЂ™t depend on the past state of inputs or outputs.Д®xcept for a small propagation delay, the output of a Combinational Logic Circuit changes immediately when there is a change in the input. The circuits we have seen till now i.e., the Multiplexers, Demultiplexers, Encoders, Decoders, Parity Generators and Checkers and so on are known as Combinational Logic Circuits.
