An electronic system is comprised of active and passive devices. When the supply is provided to the active ones for example transistors, vacuum tubes, and so on, there is the indulgence of change in the value of impedances due to voltage drops. If the common path is shared among the multiple devices, the individual currents will be drawn from the devices that are vast enough for producing the large changes in voltages. To overcome this situation, a bypass path must be established for the flow … [Read more...]
What is a Transducer : Types & Its Ideal Characteristics
Any type of electronic system requires communication with the real world. To make it done sensors and actuators are used. The purpose of the sensor is to sense the different forms of energy either it can be of movement, thermal, electrical, or magnetic. Where the actuators are used to switch currents or voltages. Sensors including actuators are termed as Transducers. The main purpose of this device is to convert the applied form of the signal into other signals based on the requirement of the … [Read more...]
What is Colpitts Oscillator : Circuit & Its Working
A circuit that produces alternating and continuous waveforms is known as an oscillator. The waveform can be a sine wave, square wave, etc. based on their output frequency, oscillators are divided into various types. Electronic Oscillators' frequency can be controlled by their input voltage, so they are termed voltage-controlled oscillators. There are many types of oscillators but mainly divided into two categories. One is Harmonic Oscillators or Linear Oscillators and the second one is … [Read more...]
What is RC Phase Shift Oscillator : Circuit Diagram & Its Working
An oscillator is a mechanical or electrical construction that produces oscillation based on some variables. This oscillator is used from clock to various metal detectors and even on computers where microprocessors and microcontrollers exist The oscillator in which the RC circuit is used as a feedback path is the RC phase shift oscillator. It generates stable sine waves that are used in low-frequency generations, particularly in the audio frequency range. The amplifier provides a phase shift of … [Read more...]
What is Band Pass Filter : Circuit & Its Working
During signal processing, a device called a Band Pass Filter or BPF is needed to allow a particular range of required frequencies and to avoid unwanted frequency ranges or components. By this filtering noise signal can be reduced by eliminating frequencies that are not required. Different types of filters like linear and nonlinear, analog, digital, active and passive, etc. are available to use based on the requirement. This article discusses an overview of Band Pass Filter. What is Band Pass … [Read more...]
What is an Inductive Reactance : Formula & Its Working
An inductor is normally a coil of wire. When current is passing through that coil, the electric field will be generated. So the field will get induced. The induced filed depends on the number of turns and this is inductance. An inductor due to its inductance resists the flow of alternating current. Basing on the Lenz's law inductor will resist change in current. Reactance is defined as the resistance offered to the AC currents by capacitors and inductors only. Usually, reactance is denoted by X, … [Read more...]
What is an Open Loop Control System & Its Working
The collection of subsystems that controls the input signal to get the desired output is known as a system. The main function of any electronic system is regulating the output and keep that within systems desired input i.e when the input of the system changes, the output of the system should respond and change according to the changed input value. In another case, if there is no change in input but the output of the system is getting disturbed then the output should respond by coming back to its … [Read more...]
What is an ACSR Conductor & Its Working
A physical medium that carries electrical energy from one place to another place is known as a conductor. The minimum conductivity and tensile strength are important factors for transmission and distribution systems. In the earlier days, the copper conductors have used to transmit the energy. But now, these are replaced with stranded hard-drawn 1350 aluminum wires to increase the tensile strength, conductivity, and efficiency. The aluminum conductors are lightweight, economical in design, and … [Read more...]
What is Arduino Sensor : Types, Working and Applications
An electronic device that senses and responds quickly to physical changes such as distance, pressure, temperature, touch can be referred to as sensors. These are used commercially in various products for temperature monitoring, alarming circuits, and in the Home automation kits, etc... In the practical world, where the motive is to design a user-friendly environment such that various devices information can be controlled, sent, and monitored. This is made possible when the multiple sensors are … [Read more...]
What is Carbon Composition Resistor & Its Working
In electronic circuits, resistors are the passive two-terminal devices used to regulate or reduce the flow of current in the circuit. Mostly fixed type resistors are used in the electronic circuits because of its fixed resistance value. The resistance is determined during the manufacturing process itself and it can't be varied like a variable type resistor. Based on the manufacturing process, the fixed type resistors are divided into 4 types such as carbon resistors, wire wound resistors, … [Read more...]
