Abstract:
The patent describes a dynamic test set for encoders whose output code is two distinctly different gray codes. The two gray codes are converted to binary, then added together and fed to a storage register. The readout from the storage register is fed to an error detection circuit which approves an allowable difference in count of plus or minus 1, plus or minus 9, plus or minus 11 and plus or minus full count. Any other difference in count will cause an alarm to be energized thereby indicating an output error from the encoder.
