In industries, master-slave digital clock is a digital clock system widely used for precise and coordinated time-keeping. In this article, we will discuss the construction, working, advantages, and applications of the master slave digital clock. Thus, let us start with the basic introduction of the master-slave digital clock. What is a Master-Slave Digital Clock? A type digital clock system which consists of a master-clock and one or more slave-clocks is referred to as a master slave digital clock. The master clock performs a function of sending a timing signal to the slave clocks, so that the slave clocks can ... Read More

A digital counter is a sequential logic circuit which counts the number of clock pulses or events that occur over time. Now, let us discuss the lockout condition in counter. What is Lockout Condition in Counter? In digital counters, the condition wherein the counter enters to an unused state and rather than coming out of this unused state to a valid state or initial state, it switches to another invalid or unused state and gets stuck up in the cycle of unused states only, is known as the lockout condition in the counter. Therefore, in the case of lockout condition, ... Read More

What is a Generalized Number System? A mathematic structure which can extend the properties of the conventional number system like integers, real numbers, rational numbers, complex numbers, etc. to a more general case is known as a generalized number system. The major applications of generalized number systems include many areas of mathematics such as algebra, analysis, number theory, topology, etc. In more simple terms, a generalized number system can be defined as the generalization of the conventional/traditional number systems. Importance of Generalized Number Systems Generalized number systems are considered an important part of modern mathematics and science because they provide ... 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

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
