Difference Between Analog Tuner and Digital Tuner
Tuners used in electrical devices to tune in to radio or television broadcasts are classified as analog or digital. A continuous waveform with varying amplitude and frequency is received and processed by an analog tuner. A digital tuner receives and processes a digital signal, which is a discrete signal consisting of 0s and 1s. Read this article to find out more about Analog Tuner and Digital Tuner and how they are different from each other. What are Analog Tuners? An analog tuner is a device that receives and tunes radio or television signals. It works by selecting a frequency from ...
Read MoreDifference Between Amps and Watts
In the world of electricity, Amps and Watts are two important units of measurement. Despite their similarities, they represent various features of electrical energy. Watt (W) is the power measuring unit. It calculates the amount of energy transferred in one unit of time. Amperes (amps) measure the flow of electricity, whereas Watts measure the rate at which that electricity is used. Read this article to find out more about Amps and Watts and how they are different from each other. What is Amps? The ampere, typically abbreviated as "amp, " is a unit of measurement for electric current named for ...
Read MoreDifference between Ammeter and Voltmeter
Both Ammeter and Voltmeter are electrical measuring instruments used for measuring the current and voltage in an electrical circuit, respectively. Read through this article to find out more about Ammeter and Voltmeter and how they are different from each other. Before getting into the differences between Ammeters and Voltmeters, let's get some basic information about these two devices. What is an Ammeter? An electrical measuring instrument that is used to measure electric current in an electric circuit is known as ammeter. As the measurement unit of electric current is ampere and this instrument is used to measure the ...
Read MoreDifference between Resistance and Reactance
Resistance and reactance are the two major parameters of an electric circuit element that together form the impedance of the circuit element. One most significant difference between resistance and reactance is that the resistance is the opposition in the flow of electric current offered by a circuit element called resistor, whereas the reactance is the opposition in the change in the magnitude and direction of the current and voltage offered by a circuit element called inductor or capacitor. The combined opposition offered by the resistance and reactance in an electric circuit is known as impedance of the circuit. In this ...
Read MoreDifference between Open Circuit and Short Circuit
A closed path following an electric current is known as an electric circuit or simply circuit. An electric circuit consists of a number of circuit components such as resistors, inductors, capacitors, etc. Sometimes in an electric circuit, two undesirable conditions occur namely open circuit and short circuit. Basically, these two states of an electric circuit are considered as faults in the circuit and hence are undesirable. In this article, we will highlight the major differences between an open circuit and a short circuit. What is an Open Circuit? As its name suggests, an open is a break ...
Read MoreDifference Between Lithium Cell and Lithium-Ion Cell
It was just two centuries ago in 1800 when Italian physicist Alessandro Volta created the first practical battery. His original battery consisted of zinc and silver stacked in alternating layers, with a piece of cloth soaked in saline between each pair of incompatible metals. The battery, often known as "Volta's pile, " was the first galvanic or primary battery. There have been several advancements in battery technology since then. The science and technology behind batteries has taken a giant leap forward in the past decade. The lithium-ion battery is one example of a newly created and widely available secondary battery. ...
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 ...
