VERFAHREN UND SCHALTUNGSANORDNUNG ZUR VERBESSERUNG DES EMPFANGS VON RADIOWELLEN.

摘要

The improved reception is attained by using several aerials. The signal received by each aerial is mixed with a carrier, generated in the receiver. The mixed signals with a controllable mutual phase position are fed to a common IF amplifier, whose output signal is evaluated and the mutual phase position of the mixed signals is controlled accordingly. In a circuit for such reception an advanced stage and a mixer are provided for the signals received by each aerial. A controllable phase rotator is provided for the mixed signals. The latter are vectorially aided in a summation circuit, whose output is coupled to the input of the IF amplifier. The amplifier output is linked to an amplitude demodulator.
