Let's start this article with a basic overview of flip-flops before moving onto discuss how they can be used as a divider circuit. What is a Flip-Flop? In digital electronics, a flip-flop (FF) is a sequential logic circuit which is used for storing 1-bit of information. As we know, in digital systems, information is represented in binary form, i.e. in terms of 0 and 1. Where, a binary 0 and a binary 1 is referred to as a bit. A flip-flop is a 1-bit memory cell that stores information in terms of 0 or 1. Therefore, flipflop is the fundamental ... Read More

Let's start this article with some basics of flip-flops before moving onto discuss their triggering methods. Flip-Flops in Digital Electronics In digital circuits, a flip-flop is a sequential logic circuit which is used to store 1-bit of information. A flip-flop has one or more inputs and two outputs. It also has an input for provide a clock signal. Flip-flop is a fundamental building block of digital circuits. Hence, flip-flop is also referred to as an elementary memory element in digital systems. Flip-flops find their applications in computer memory, registers, counters, and many other digital systems and circuits. A flip-flop ... Read More

In digital circuits, a latch is a sequential logic circuit which has two stable states. Hence, a latch is also called as a bistable-multivibrator. A latch has capacity to store 1-bit of information. A latch has one or more inputs and two outputs. The outputs of a latch are specified by Q and Q'. Where, Q is the normal output of the latch and Q' is the inverted output. The block diagram of a latch is shown in Figure-1. In this article, we will discuss about the edge triggered latches, their types, applications. So, let us start with the ... Read More

Let's start this article with a brief overview of basic flip-flops before moving onto discuss a special type of flip-flop called edge-triggered flip-flop, how it works, its types and applications. What is a Flip Flop? In digital electronics, a flip-flop (FF) is a sequential logic circuit which is used for storing 1-bit of information. As we know, in digital systems, information is represented in binary form, i.e. in terms of 0 and 1. Where, a binary 0 and a binary 1 is referred to as a bit. The flip flop is a 1-bit memory cell that stores information in terms ... Read More

In digital electronics, a set of flip-flops that changes its states in response to pulses applied at the input is called a digital counter. In the digital counter circuit, the flip flops are connected in such a way that their combined state at any time is the binary equivalent of the total number of pulses that have occurred up to that time. Therefore, as its name implies, a counter is used to count pulses in a digital system. Digital counters are classified into the following two types namely, Asynchronous Counter − The type of counter in which the flip ... Read More

What is SR Flip-Flop? SR flip-flop is a simple 1-bit storage element which has two inputs namely S and R, and two outputs, i.e. Q and Q'. Where, S specifies Set input and R specifies Reset input. The output Q is the normal output and the Q' is the complemented or inverted output. In addition to SR inputs, the SR flip flop also has a clock input which is used for triggering the circuit. The block diagram of SR flip flop is shown in Figure-1 below. The operation of the SR flip flop can be analyzed using its truth ... Read More

What is a JK Flip-Flop? JK flip flop is also a 1-bit storage device having two inputs similar to SR flip flop, but it has inputs denoted by J and K instead of S and R. It has two outputs viz. Q (normal output) and Q' (inverted output). The clock signal is used for synchronization of the circuit. The block diagram of the JK flip flop is shown in Figure-1 below. The operation of the JK flip flop can be understood with the help of its truth table which is given below − Inputs Output ... Read More

In digital electronics, a binary counter is a type of sequential logic circuit which is able to count in binary numbers. A binary counter can counter from 0 to 2(n-1), where n is the total number of bits in the counter. Basically, a binary counter is a type of digital circuit which counts the number of clock pulses that occur over a time period. The binary counters are built up of flip flops, where a flip flop is a most elementary memory element that can store 1-bit of information. In a binary counter, each flip flop represents one bit of ... Read More

Read this article to learn how you can implement a two-variable Boolean function using a 4:1 multiplexer. Let's start with a brief introduction of two-variable Boolean functions and multiplexers. What is a Two-Variable Boolean Function? A two variable Boolean function is a logical expression which has two input variables. Where, each variable can take either a binary 0 or a binary 1 as its value. A two variable Boolean function can have 4 possible combinations of variables, i.e. in SOP form, $\bar{A}\bar{B}, \bar{A} B, A \bar{B}, AB, $ with minterm designations m0, m1, m2, and m3. In POS form, $(A+B), ... Read More

Karnaugh Map (K-Map) K-Map is a graphical tool used for simplifying Boolean expressions represented in their standard form to obtain their minimal form. The K-Map is basically a graph or chart that composed of an arrangement of adjacent cells or squares, where each cell represents a particular combination of variables of the function either in sum or product form. The number of cells in the K-Map depends upon number of variables in the Boolean function, i.e., K-map has 2n adjacent cells, where n is the number of variables in the Boolean expression. Therefore, the number of cells in a 2 ... Read More
