Hello everyone, I am Rose. Today I want to introduce amplifier to you. An amplifier is a device that can amplify the voltage or power of an input sign...
the transformer could be much smaller and a heat sink would not be required. Clearly, there never will be a 'no-waste' amplifier, but the more efficient an amplifier is, the lighter and smaller it can be. So in live sound, where power amps are ...
Let us consider a practical example of solid state relay as shown in the figure below. If the output switch is opened or MOSFET is off, then it is said to have infinite resistance. Similarly, if the output switch is closed or MOSFET conducts, then it is said to have a very low resist...
This crossover distortion makes the Class B amplifier unfit for directly amplifying audio signals. The output stage of Class B is often coupled with the load or speaker by a transformer to minimize distortion. Class B amplifiers work fine at radio frequency amplification. The crossover distortion ...
1. The function of impedance and voltage conversion, the output of the audio cow in the amplifier will have impedance changes, then the inevitable voltage will also change, achieving impedance matching before and after. 2. The audio signal is coupled. Because the output of the audio transformer...
(AC) power output. However, it is not recommended to directly transfer the electrical current through the output device. Therefore, to achieve this goal, a specific configuration is applied by using a suitable transformer to establish a connection between the load and the amplifier, as seen in ...
An inductor is a passive electrical component that opposes sudden changes in current. Inductors are also known as coils or chokes. Contact us to learn more.

LVDT (linear variable differential transformer)transducers are used to measure linear displacement/position over relatively short distances. They consist of a tube that contains a rod. The base of the tube is mounted to a fixed position, and the end of the rod is affixed to something that moves...
