Abstract: The presence of a d.c. offset in the input signal to an adaptive equalizer for a high speed modem must be removed before a valid signal enters the equalizer if the "coefficient up-date" algorithm for the equalizer is not to be confused. Normally the d.c compensation is achieved using adjust-on-test resistors or potentiometers which provide for in life adjustments to compensate for ageing drift. The submission envisages the use of an additional adaptive equalizer tap-stage connected to a fixed voltage source. This voltage is multiplied by the additional tap-stage multiplier and summed with the outputs of the other tap-stages in the equalizers accumulator. The error produced from the equalizer decision circuit is correlated with the fixed voltage in the additional tap-stage correlator the output of which controls the gain of the additional tap-stage multiplier thereby compensating for the original d.c. offset of the output of the equalizer accumulator.

Abstract: The terminations from the energising coils (12) of an electric motor stator (10) are directly connected to terminals (15-20) provided on a first component (14) attached to the stator. A second removable component (24) is provided with corresponding terminals (15A-20A) which mate with those of the first component so that the two components form a plug and socket unit. The terminals (15A-20A) of the second component are connected with other elements of the energising circuit such as power leads (28A, 29A) capacitor (35) and speed change switch (30,52), thereby simplifying and rationalising the construction of the external part of the energising circuit.
