Abstract
Data generated by an encoder with phase quadrature outputs, for instance a displacement transducer in a resistance spot welder control system, is read out of the interface to the computer in a format compatible with computer languages. The quadrature signals are converted to pulses representing positive and negative unit changes of displacement, and fed to an up-down counter which has signed two's complement values at its output. The most recent displacement data is read out while the counter continuously tracks the encoder.
