· Encoder speed can be determined by either of two methods: pulse counting or pulse timing. Refresher on quadrature encoding. Incremental encoders often output signals on two channels – typically termed "A" and "B" – offset by 90 degrees (in quadrature). The direction of rotation can be determined by which channel is leading.
