Race-around Condition in JK Flip-flop
Let's start this article with a brief introduction of JK flip-flop and its block diagram and truth table, before moving on to discuss the race-around condition. JK Flip-Flop JK flip-flops is a one-bit storage device which has two stable states. The block diagram representation of a JK flip-flops is shown in Figure-1. It has two inputs specified by "J" and "K", one clock input for synchronization of the circuit, and two outputs represented by Q and Q'. When clock signal is absent, the output of the JK flip-flop is independent of the inputs J and K. When the clock ...
Read MoreDecoder for Active Low and High Output
What is a Decoder? In digital electronics, a decoder is a combinational logic circuit which is capable of converting information in binary form N inputs to a maximum of 2N outputs. The block diagram of a typical decoder is shown in Figure-1. It can be seen that a decoder has N input lines to accept binary coded information, an enable input, E to turn on or off the decoder (optional), and 2N unique output lines. The digital decoders are extensively used in several applications in the field of digital electronics such as decoding of data, seven segment displays, data ...
Read MoreDecoder Driver IC and Its Application
What is a Decoder Driver IC? A type of integrated circuit (IC) which is designed to decode information specified in the binary form is known as decoder driver IC. A decoder driver IC generates output signals to drive different electronic devices like LEDs, electronic relays, electric motors, etc. Decoder driver ICs are most commonly used in electronic systems to convert digital signals specified in binary form into specific output signals that then drive an output device. Types of Decoder Driver ICs Depending on the decoding function performed, there are several types of decoder driver ICs available. Some important types are ...
Read MoreCompletely and Incompletely Specified Logic Functions
What is a Logic Function? In digital electronics and Boolean algebra, an expression that have some operations performed on the binary inputs to produce an output in the binary form is called a logic function. Logic functions are also called Boolean functions. Depending on the specified output, there are two types of logic functions namely, Completely specified logic functions Incompletely specified logic functions Now, let us discuss the completely and incompletely specified logic functions individually in detail. Completely Specified Logic Function A logic function or Boolean function which is defined for all possible combinations of input variables is ...
Read MoreCascading of Decoders
What is a Decoder? A decoder is a combinational logic circuit that converts an N-bit binary input code into a 2N output lines such that only one output line will be active for each one of the possible combinations of inputs. The block diagram of a decoder is shown in Figure-1. Here, A, B, C, etc. are the input lines, Y0, Y1, Y2, … etc. are the output lines, and E is the enable input of the decoder. In this article, we will discuss cascading of decoders. Cascading of Decoders means the process of realizing a higher order decoder ...
Read MoreMaster Slave Digital Clock
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 MoreLockout Condition in Counter
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 MoreGeneralized Number Systems
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 MoreFlip-Flop Used as a Divider Circuit
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 MoreEdge-triggered Latches
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 ...
