…There are wireless repeaters that use space as a transmission medium, and wired repeaters that use wires such as coaxial cables and optical fiber cables as a transmission medium. They are also classified into analog and digital repeaters according to the transmission method. Analog repeaters are linear amplifiers with gain that compensates for losses and distortions in the transmission path, and although the circuit scale is small, when repeaters are connected in multiple stages, the noise and distortion generated by each repeater are added together. … *Some of the terminology that refers to "analog repeaters" is listed below.
