In the field of wireless communication, the signal strength must be increased to transmit the signal for long distances. So this can be made possible by using the amplifier. It enhances the strength of the signal without altering the information. Amplifiers are of various types based on the frequency ranges and applications. The required ones are selected and placed in the circuit. For audio signal amplifications, audio amplifiers are used. The audio amplifiers are not capable enough of … [Read more...]
What is Dielectric Material : Types, Properties & Applications
The materials used in the electronic industry are classified based on the conduction of electricity. These are of three types, they are conductors, semiconductors, and Insulators. The purpose of dielectrics is to prevent the conduction of electricity. These resemble the functionality of insulators. The very famous application of dielectric material is observed in the capacitors. Because the conducting plates are separated by a non-conducting media known as insulating material. Based on the ty … [Read more...]
What is Analog Modulation : Types & Its Applications
Conveying of our messages to someone happens through voice, few gestures, expressions. This is the human way of communication. Whereas in the technological context, there are multiple ways of transmitting messages either in the form of audio, digital bits and baseband signal transmissions. The fundamental method of transmission is telecommunication and modulation is the core system for any of the telecommunication devices. These days, the standard forms of communication devices are co-axial … [Read more...]
What is Diode Approximations : Types & Its Problem
Diode Approximations are how the Diodes present in the circuit gets analyzed. The diode can be considered as the basic electronic device in any type of circuit. These are of various types a design criterion is based on the requirement. The analysis of it can be done based on the Three approximations. Each approximation can be done by considering the diode as a switching element. For these basic components called Diodes, there exist three approximations. In each one, the initial and the … [Read more...]
What is Megger : Construction, Working and Its Applications
It is quite easy to measure the resistance of a resistor. However, measuring the resistance of an insulator can be a difficult task. This is because the resistance of insulators is extremely high. For that, a device called megger is used which can be used to measure the relatively high value of resistance of insulators. The resistance is measured by comparing the unknown resistance of the insulator to that of the known value of resistance of a material. The circuit comprises two voltage coils … [Read more...]
What is Resistance Thermometer : Construction & Its Working
A Thermometer is a device that is used in the measurement of temperature. A resistance thermometer is a type of thermometer which can be used to give extremely accurate results. The temperature is measured by measuring the change in resistance. The thermometer consists of a platinum wire placed inside glass probes. The device is evacuated to prevent an unnecessary rise in temperature. The device is extremely fragile and hence kept within protective probes. They have extremely high accuracy and … [Read more...]
Difference between LVDT and RVDT and Its Advantages
Linear Variable Differential Transformer (LVDT) and rotary variable differential transformer (RVDT) is an electrical transformer type sensor used to measure the linear displacement and angular displacement respectively. The circuit diagram and working principle is similar to each other but differentiated in terms of core and shaft movements inside the module. These sensors are also called as electromechanical transducer due to the fact that it yields variable alternating current (AC) output … [Read more...]
What is Half Subtractor : Working and Its Applications, K-MAP, Circuit using NAND Gate
To process the information like light or sound from one point to other we can use analog circuits by giving proper inputs in the form of analog signals. In this process, there are chances of noise being picked up by the input analog signals and this may lead to loss in the output signal, it means whatever the input we are processing at the input level is not equal to the output stage. To, overcome these digital circuits are implemented. Digital circuit can be designed with logic gates. Logic … [Read more...]
Sum of Products and Product of Sums : Types and Schematic Diagrams
We are all more familiar with the terms SUM and PRODUCT in mathematics. Based on these terms, AND and OR logical operations are derived. Any kind of logical expression can be represented through these terms and there are many ways of expressing a logical function. AND represents the product relationship between the terms whereas OR represents sum relationship. So, Sum of Products and Product of Sums are the equivalent approaches of representing a logical expression. Through few principles, these … [Read more...]
What is a Bypass Capacitor : Types, Functions & Its Applications
A capacitor is a device that can be used to store electric energy. It has two terminals and its effect is called capacitance. A capacitor basically consists of two metal plates that act as a conductor with a dielectric medium in between. The conductor may be in the form of electrodes or metal plates or thin foil. The dielectric material is used to increase the capacitance. There are different types of capacitors and a bypass capacitor is one of them. It is a component in an electric circuit that … [Read more...]
