As an electro-mechanical device, an encoder is able to provide motion control system users with information concerning position, velocity and direction. There are two different types of encoders: linear and rotary.
1 Binary decoder, digital circuits such as 1-of-N and seven-segment decoders. 2  Decompressor (compression decoder), converts compressed data (e.g., audio/video/images) to an uncompressed form. 3  Instruction decoder, an electronic circuit that converts computer instructions into CPU control signals.
