Abstract
An improved error correcting circuit that is adapted for correcting errors in data to be transmitted over communication links which require a minimum density of 1's to preserve timing on the transmission link is described. The circuit utilizes an error correcting code which converts a data word into two encoded words. Neither of the encoded data words is 0 for any of the possible values of the data word.
