Abstract: SPACE DIVERSITY RECEIVER WITH COMBINED STEP AND CONTINUOUS PHASE CONTROL           Abstract of the Disclosure Prior art circuits used in space diversity systems for combining the two received signals employ either continuously variable phase shifters, which have return-to-zip problems, or 90 degree phase steppers which combine the signals to within ? 45 degrees.  Both of these limitations are avoided by the use of the combination of a continuously variable phase shifter (14) and a 90 degree phase stepper (13).  Control means (19, 20) are provided for actuating the stepper when the phase shift introduced by the variable phase shifter reaches a prescribed limit.

Granted: 1981-12-08
Abstract: ABSTRACT     A subscriber line circuit comprises two electronic circuits for supplying the subscriber set with feed current via the telephone pair, and for simulating an inductive impedance.  The circuits detect current variations on the line due to signalling conditions at the subscriber set.  Two hysteresis threshold comparators recognize voltage variations in the electronic circuits due to signalling conditions, and emit corresponding driving currents when the variations lie within a predetermined range.  In this way, interference problems arising from the use of a common power supply for a number of subscriber sets are eliminated by relatively simple circuitry.
