Flip-flops are synchronized sequential circuits. They are used as a memory that can store either logic-1 or logic-0. Flip-flop is more reliable than latch as it has a clock or an enable pin that controls the output state. If enable pin is not active, it does not let the output state change even if the … Read more
Flip flop is one of the most important parts of digital electronics. Flip-flops are synchronized memory elements that can store only 1 bit. The output of the flip-flop depends on its inputs as well as its past outputs. Depending on the control inputs used, there are 4 types of flip-flops – SR flip-flop, D flip-flop, … Read more
Electronics engineering is one of the popular domains of engineering. We can not imagine our modern society without electronics. Whether it is your television, smartwatch, or the device on which you are reading this article, are all electronic products. Some devices such as a lamp, fridge, air conditioner, music player, audio recorder, etc. have electronics … Read more
In combinational circuits, we deal with the devices whose output depends solely on the present inputs and not on the past inputs. Logic gates, encoder, decoder, multiplexer, demultiplexer are examples of such combinational logic circuit elements. Here we are going to discuss Encoder and Multiplexer. They have a few things in common such as, both … Read more
Digital electronics consists of combinational circuits and sequential circuits. Combinational circuit elements are the ones whose output depends on the present inputs and do not depend on the past inputs. Logic gates, decoder, encoder, etc. are examples of the combinational circuit element. Here, we are going to discuss two of such circuit elements. Multiplexer and … Read more
A signal is a time-varying entity that carries some information from source to destination. Signals can be of many types such as electrical signal, sound signal, light signal, etc. In electronics, communication, and electrical engineering, we care about the electrical signals the most. For transmission of any other signals, we first need to convert them … Read more
In digital electronics, we classify circuits into two primary types which are – combinational circuits and sequential circuits. In the case of combinational circuits, the output depends only on the present input. Whereas, in the case of the sequential circuits, the output depends on the present input as well as the past output(s)/input(s). Due to … Read more
Boolean algebra is a set of rules which are used to simplify the given logic expression without changing its original functionality. So in this article, we are going to learn about Boolean algebra. The Boolean algebra was invented by George Boole; an English mathematician who helped in establishing modern symbolic logic and whose algebra of … Read more
A Latch is a basic memory element that operates with signal levels (rather than signal transitions) and stores 1 bit of data. Latches are said to be level sensitive devices. Latches are useful for storing information and for the design of asynchronous sequential circuits. SR Latch The SR latch is a circuit with two cross-coupled … Read more
In Sequential Circuits, the present output depends on the present input as well as past output(s). It consists of a combinational circuit and memory elements. A block diagram of a sequential circuit is shown in Fig.1. It consists of a combinational circuit to which storage or memory elements are connected to form a feedback path. … Read more
