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: 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 …
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: A full wave rectifier is a rectification circuit that is used to change the overall ac signal that is applied across its terminals into a pulsating dc form. We know that rectification is nothing but the conversion of ac signal into dc. However, basically there exist two types of rectifiers, the first one is …
Definition: A Half-Wave Rectifier is a device that converts only one half of the applied ac signal into pulsating dc. The other half of the applied ac signal gets suppressed by the rectifier circuit. A half wave rectifier circuit uses only a single diode, due to the unidirectional current flow property of the diode. We …
One of the major differences between LED and photodiode is related to their operating principle. An LED is a device that works on the principle of electro-luminance. While the operation of a photodiode depends on the principle of photoconduction. Basically when an external potential is provided then a light emitting diode gives off light. Whereas …
Both resistor and capacitor are passive components that are employed in electrical and electronic circuits. However, the crucial difference between the resistor and the capacitor is that a resistor is an element that dissipates electric charge or energy. As against, a capacitor is an element that stores electric charge or energy. Basically, a resistor is …
Both transistor and thyristor are the types of semiconductor devices. But some factors exist that differentiates the two. The crucial difference between transistor and thyristor is that a transistor is a 3-layer device that requires regular current pulse in order to ensure conduction. On the contrary, a thyristor is a 4-layer device that needs an …
Definition: An oscillator is basically a signal generator that produces a sinusoidal or non-sinusoidal signal of some particular frequency. Oscillators find their various applications as these are the fundamental component of any electrical and electronic circuits. Continuous oscillations are the basis of working of an oscillator. Sometimes, an oscillator is said to be an amplifier …
Both intrinsic and extrinsic semiconductor is the 2 categorizations of semiconductor material. The difference between intrinsic and extrinsic semiconductor is that Intrinsic semiconductors are the pure form of semiconductor materials. Whereas extrinsic semiconductors are impure semiconductor formed by adding an impurity to a pure semiconductor. No, any external impurity is doped in case of an …
