Introduction of encoder ！

An encoder is a hardware / software device that converts analog video signals (such as bit streams) or data into digital signals that can be used for communication, transmission, and storage. Encoder applications are widely used to detect the speed, position, angle, distance or count of mechanical motion encoder. In addition to being used in machinery, many motor controls, such as servo motors, are equipped with encoders for motor controllers , Speed and location of the detection
