What is a Digital Counter : Types & Applications
A Digital Counter is obtained by arranging the flip-flops. These are the applications of flip-flops. Other than counting, these are used for measuring the frequency as well as time. These are used to increase the addresses in memory. The operation of these devices depends on the single clock applied. These are made of flip-fops as basic elements. There are two states included in the flip-flops. The high state is represented by 1 and the low state by 0. The operation of the counter can be made … [Read more...]
What is Snell’s Law : Definition & Its Derivation
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
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
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 Wave Analyzer : Working & Its Applications
In electronics and communications, the periodic signal is represented in the form of DC component and some sinusoidal harmonics. It is necessary to analyze the harmonics present in the signal. So, wave analyzers are used to measure the amplitude of the harmonics in the domain of frequency with the help of tuned filters and voltmeters. The wave analyzer can be tuned to analyze the frequency of the harmonic component of the signal whose amplitude is to be measured. Here is a complete description … [Read more...]
What is Transformer Coupled Amplifier & Its Working
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
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 Color Sensor : Working & Its Applications
In electronics, sensors are the devices or modules or detectors or subsystems used to detect and respond to electrical and optical signals. Sensors can covert physical quantities like temperature, humidity, speed, etc into an electrical signal and send the information to the other electronic devices like the processor. Sensors are classified into various types to measure temperature, capacitance, heat, resistance, etc. They are a temperature sensor, proximity sensor, accelerometer, touch sensor, … [Read more...]
What is RGB LED : Circuit & Its Working
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...]
