8051 microcontroller is an 8-bit microcontroller created in 1981 by Intel Corporation. It has an 8-bit processor that simply means that it operates on 8-bit data at a time. It is among the most popular and commonly used microcontroller. As it is an 8-bit microcontroller thus has 8-bit data bus, 16-bit address bus. Along with …
Definition: Half adder is a combinational circuit that is used to add two binary numbers of one-bit each. It does not hold the ability to consider the carry-in generated from previous summations. The addend, when added with the augend, provides sum and carry (if present). Half adders are used in addition of LSB of the …
Definition: A Half subtractor is known as a combinational circuit that produces a difference of two, 1-bit binary numbers. More specifically we can say, that it subtracts the two binary values at its input in order to generate a difference of the two values at its output using a borrow bit if required. Thus the …
Definition: Vector processor is basically a central processing unit that has the ability to execute the complete vector input in a single instruction. More specifically we can say, it is a complete unit of hardware resources that executes a sequential set of similar data items in the memory using a single instruction. We know elements …
Definition: A circuit that is capable of sampling the input signal applied to its terminal as well as holding the sampled value up to the last sample for a particular time interval is known as sample and hold circuit. It basically utilizes an analog switch and a capacitor to perform the task. The circuit samples …
Definition: Gray Code is the minimum-change code category of coding in which, the two consecutive values changes by only a single bit. More specifically we can say, it is a binary number system where while moving from one step to the next, only a single bit shows variation. This coding technique was invented by Frank …
Definition: Octal number system is a base 8, digital number system. This number system has 8 numbers starting from 0 to 7 in its range. The numbers 0, 1, 2, 3, 4, 5, 6, 7 holds similar meaning as that in case of the decimal number system. Oct means 8 and this is a number …
Definition: Hartley oscillator is a type of LC oscillator that generates undamped sinusoidal oscillations whose tank circuit consists of 2 inductors and a capacitor. In the tank circuit, the two inductive coils are serially connected together forming a parallel combination with the capacitor. Hartley Oscillator was invented by Ralph Hartley in 1915 and hence named …
Basically, electricity is measured either in the form of current or voltage. The crucial difference between Voltmeter and Ammeter is that a voltmeter is a device that determines the difference in electric potential between 2 points in the circuit. As against an ammeter determines the amount of electric current flowing through the circuit. In this …
Definition: Superposition Theorem states that voltage or current through an element of a linear, bilateral network having multiple sources is equivalent to the summation of generated voltage or current across that element, independently by each source present in the network. While at the time of considering a single source all other sources are replaced by …
