A quadrature encoder, also known as a 2-channel incremental encoder, converts linear displacement into a pulse signal. By monitoring both the number of pulses and the relative phase of the two signals, users can track the position, direction of rotation, and speed. In addition, a third channel, or index signal, can be used to reset the position counter.
