What is a Low Pass Filter : Circuit & Its Working

August 10, 2020 By WatElectronics

Low Pass Filter Circuit Diagram

In electronic devices, the filters are the circuits that allow desires frequency components and blocks all other frequency components of a signal. For example, in radio or tv, a tuning filter circuit rejects unwanted frequencies by allowing only the desired channel. Filter circuits are divided into four types based on the range of frequencies that the circuit would allow while blocking all other frequencies. They are low pass filters, high pass filters, bandpass filters, and bandstop filters. … [Read more...]

What is High Pass Filter : Working & Its Applications

August 7, 2020 By WatElectronics

High Pass Filter

Filters are the electronic circuits that allow particular frequency components and attenuate the unwanted frequency components of an input signal. These are found in various electronic applications to allow a particular range of frequencies of a signal. Basically, filters are divided into two types based on the type of components used in designing and operation. They are Passive filters and Active filters. Depending upon the range of frequencies, filters are categorized into 4 types. They are … [Read more...]

What is Full Adder : Circuit using Basic Gates

July 31, 2020 By WatElectronics

Full Addder

Nowadays, digital electronic devices have a wide impact on our living. In our day to day activities, we use cell phones, PDA's, and many more. These comprise comparators, Dividers, Adders, etc. The functionality and performance of this mainly depend on how efficiently these basic circuits operate. Full adder is beneficial in terms of the addition of multiple bits. Each circuit has its advantages and limitations based on the power supply and the propagation delay. Full Adder is the basic … [Read more...]

What is Snell’s Law : Definition & Its Derivation

July 27, 2020 By WatElectronics

Snell's Law

Initially, Ptolemy a scientist from Alexandria discovered the relation that exists between refraction angles, but his invention failed for a minimal range of angles. In the scope of this Alhazen invented the law of refraction and finally, it was named Snell by the Persian researcher Ibn Sahl. After this many inventors worked upon this law to know the exact principle of this law. Finally, with the enhancement of various electromagnetic and optical concepts, Snell’s law was brought into the modern … [Read more...]

What is Hartley Oscillator : Working and Its Applications

July 19, 2020 By WatElectronics

Hartley oscillator

An electronic oscillator in which the oscillator frequency is determined through a tuned circuit consisting of inductors and capacitors is called the Harley oscillator. The invention of the Harley oscillator circuit was done in 1915 by Ralph Hartley, an American engineer. This oscillator is a type of harmonic oscillator. The Hartley Oscillator produces the waves of radio frequencies therefore it is also referred to as radiofrequency oscillators. The tank circuit of the oscillator having a … [Read more...]

What is Common Source Amplifier : Working & Its Applications

July 17, 2020 By WatElectronics

Common Source Amplifier

In electronic circuits, amplifiers are used to increase the strength or amplitude of the input signal without any phase change and frequency. Amplifier circuits are made up of either FET (Fied Effect Transistor) or normal bipolar junction transistor-based on their 3 terminals. The advantage of amplifier circuit using FET over BJTs is used as small-signal amplifiers because they produce high input impedance, high voltage gain, and low noise in the input signal. FET is a voltage-controlled device … [Read more...]

What is Transformer Coupled Amplifier & Its Working

July 11, 2020 By WatElectronics

Transformer Coupled Amplifier

In multi-stage amplifiers, coupling devices are used to connect different stages of transistor circuits in cascade. When the output of the first stage is connected to the input of the second stage through a coupling/coupled device, then it is referred to as a coupled amplifier. The coupling devices would be a transformer or resistor or capacitor. Based on these devices, there are different types of coupling amplifiers/coupled amplifiers such as Direct-coupling amplifier, RC coupled amplifier, … [Read more...]

What is an Inductive Transducer : Working & Its Applications

July 9, 2020 By WatElectronics

Inductive Transducer

A device that can convert one form of energy into another form is called a transducer. That means a transducer has the ability to convert a signal of one form to another form. These are mainly used for automation, measurement, and control systems because the electrical signal needs to be converted to physical quantities like force, torque, motion, etc. An electric motor, solar cell, incandescent bulb, microphone, etc are examples of transducers. A transducer can be electrical or mechanical. An … [Read more...]

What is RGB LED : Circuit & Its Working

July 4, 2020 By WatElectronics

RGB LED

The term LED stands for Light Emitting Diode. In electronic circuits, the LED is a type of PN-junction semiconductor diode, which can emit light when current flows through the circuit in the forward direction. This indicates whether the electronic device is working or not. LEDs are widely used in various applications such as in cars, bikes, home appliances, offices, lighting, mobiles, televisions, etc. Usage of Multi-colored LEDs in the device reduces, cost, power and emits more than one colored … [Read more...]

What is Cascode Amplifier : Circuit & Its Working

June 30, 2020 By WatElectronics

Cascode Amplifier

Cascode is a technique implied to improve the performance of the analog circuits. The same technique can be applied to transistors and the vacuum tubes to make the circuit better performance-wise.   The word cascode is initiated in the year 1939 by Frederick Vinton Hunt's and Roger Wayne Hickman's article during the discussion of voltage stabilizer applications. The discussion was about to propose a method to replace the pentode by cascoding two triodes. In cascoding, two transistors are used … [Read more...]
