![]() Synchronous Sequential Circuits − A digital circuit in which the change in the state of memory element is synchronised by the clock signal.Įxamples of sequential circuits − Latches, Flip-Flops, Counters, Registers, etc. The memory element is used to store the past history of the circuit operations.Īsynchronous Sequential Circuits − Do not use clock signals, instead the circuit is driven by the pulses of input signal. The sequential circuits are designed in a way that their output depends upon both the present and past inputs. The sequential circuits consist of combinational circuits and a memory element. Data Transmission − Encoder, Decoder, Multiplexer, Demultiplexer.The implementation of combinational logic circuits is made in such a way that is output depends upon the present inputs only and it is not affected by the past history of the circuit operations.Ĭircuits to perform Arithmetic and Logical operations − Adder, Subtractor, Comparators, Programmable Logic Devices etc.Ĭode Converters − BCD, Binary, 7-Segment Display The logic gates are generally designed using diode, transistors and other electronic components.Ĭombinational circuits are designed using various logic gates. Types of Digital CircuitsĪ logic gate is an electronic component that is implemented using a Boolean function. Digital Circuit DefinitionĪ circuit implemented using a number of logic gate and takes the input in the binary form (0’s and 1’s) is called as Digital Circuit. The digital circuits are implemented using logic gates like AND, OR, NOT, NAND, NOR, XOR and XNOR which can perform logical operations. ![]() The digital signals are the signals which are represented using the binary language, i.e., 0’s and 1’s. Digital electronics is branch of electronics which deals with digital signals to accomplish the tasks.
