Incompletely Specified Functions in Boolean Algebra
What is an Incompletely Specified Function? In Boolean algebra, a Boolean function or logic function whose output values are known for a subset of its inputs and has output which is a don’t care condition for at least one of its input combinations is called an incompletely specified function. Hence, in an incompletely specified function, the value of the function for don’t care combinations can be selected either a 0 or a 1 depending on the fact that which one leads to be the more minimal solution of the function. For these combinations, the Karnaugh map (K-Map) entry is marked ...
Read MoreBasic MOS Transistors
MOS stands for Metal Oxide Semiconductor. Metal Oxide Semiconductor is used for constructing transistors which are called MOSFET (Metal Oxide Semiconductor Field Effect Transistors). MOS transistors are being extensively used in a variety of modern electronic and power electronic devices like inverters, microprocessors, memory ICs, digital logic circuits, and more. What is a MOS Transistor? A MOS (Metal Oxide Semiconductor) transistor is a type of field effect transistor (FET) that can operate in both depletion mode and enhancement mode. A MOS transistor typically consists of three-terminals namely, Gate (G), Source (S), and Drain (D). The major parts of a MOS ...
Read MoreBipolar-Output D/A Converters
In digital electronics, a D/A converter, also called Digital-to-Analog Converter, is an electronic device that converts digital signal inputs into analog signal outputs. Depending on the polarity of output signals, D/A converters can be classified into two types namely, Unipolar-Output D/A Converters and Bipolar-Output D/A Converters. A unipolar-output D/A converter can produce only positive analog signals as output, whereas a bipolar-output D/A converter can produce both positive and negative analog signals as output. In this tutorial, we will discuss bipolar-output D/A converts, along with their construction, types, working, advantages, and applications. So, let’s start with the basic definition ...
Read MoreBlock Coding in Digital Electronics
In digital electronics, block coding is a technique of encoding data into a specific format. It is mainly used to detect and correct errors occurred in the information during transmission and storage. This is done by adding a block code of redundant information to the main data. Block coding is mainly employed to create a robust method of data transmission and storage. In the block coding, data is encoded by splitting it into multiple blocks of a fixed size and applying encoding techniques to each of these blocks separately. In block coding, the input data is taken ...
Read MoreDifference between Volt and Amp
Voltage and amperage are both significant topics in electrical engineering. While they are related, they are relevant to different electrical circuit features. Voltage and current are two important electrical concepts. Voltage, measured in volts (V), is the potential difference between two points in a circuit that drives current flow. The flow of electric charge through a conductor is referred to as current, which is measured in amperes (A or amps). Read this article to find out more about Volt and Amp and how they are different from each other. What is Volt? Voltage is a fundamental term in electricity that ...
Read MoreRace-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 ...

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 ...
