Sometimes, while performing electrical operations, it becomes important for us to isolate one part of the circuit to another to prevent excess loss of energy. For that reason, we use an isolation amplifier which acts as an isolating device. The main purpose of the isolation amplifier is to electrically separate the circuit which comes before the amplifier from the circuit which comes after the amplifier. So, basically we can say that an isolation amplifier can be used to give ohmic isolation … [Read more...]
What is Touch Sensor : Working & Its Applications
Even if a human body touches something, instantly the surface information will be passed to the brain using senses. Touch can also be felt by animals and plants. Hence the same technique can also be implied in today's electronics. Electronic devices consist of various sensors like temperature, pressure, humidity, etc. Similarly, a sensor related touch device is also designed. Nowadays, we are coming across the user interfaces that are operated on a single touch. There is a wide range of … [Read more...]
What is Tuned Amplifier : Types & Applications
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, Woking 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...]
