Abstract
Apparatus is described for monitoring and, if necessary, correcting the polarity of a transmitted data signal. Syndrome signals are produced in accordance with the error pattern of the transmitted data signal. Coincidences between block timing pulses and the syndrome signal and block timing pulses and an inverted syndrome signal are counted, and when the respective counts reach predetermined levels counted output signals are produced. A polarity signal indicating proper or improper data signal polarity is produced from the counted output signals. The polarity of the transmitted data signal is adjusted in accordance with the value of the polarity signal.
