Attenuator

An attenuator is an electronic device used to reduce signal strength and is widely used in communications, broadcasting, testing, and other fields. Its main function is to reduce the power or voltage of a signal without significantly changing the signal waveform. Its main uses are: (1) adjusting the size of the signal in the circuit; (2) in the comparison method measurement circuit, it can be used to directly read the attenuation value of the network under test; (3) improving impedance matching.
