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 …
Definition: Karnaugh Map usually abbreviated as K-map is a systematic approach used for simplifying Boolean expressions or logic functions. It is majorly used method for minimizing the Boolean expressions. K map is basically known to be a different method for the representation of truth table. The Karnaugh map (K map) according to the variables involved …
Definition: A Quantizer is a device that changes the sampled input signal into quantized signal that has some predetermined fixed voltage levels. The level of the quantizer depends on the encoder. As the bit value of encoder decides the quantization level. Suppose in the circuit has the 2-bit encoder, then n will be 2. Thus …
Both active and passive elements are part of electrical and electronic circuits. But various factor exists that differentiates the two. The crucial difference between active and passive elements is that an active component holds the ability to supply energy to the circuit. As against, a passive component is not able to give the energy to …
Definition: Capacitive transducers are passive transducers that determine the quantities like displacement, pressure and temperature etc. by measuring the variation in the capacitance of a capacitor. As we know that a transducer changes a form of energy into another form. So, in the capacitive transducer, the change in the capacitance is used to measure the …
Definition: Noise in a communication system is basically undesirable or unwanted signals that get randomly added to the actual information carrying signal. Resultantly, causes disturbances in the original signal being transmitted from an end to another. The presence of noise in the system causes interference in the signal being transmitted and this ultimately causes errors …
