Abstract

443,582. Wireless receiving-apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and WRIGHT, G. M., Little Baddow, Chelmsford. Aug. 30, 1934, No. 25024. [Class 40 (v)] In a homodyne receiver in which the added carrier frequency is obtained by selecting and amplifying received energy, the necessity for isolating the two receiving circuits from one another is avoided by the use of aerials so arranged as to be uncoupled. As shown, mutually perpendicular frame aerials may be used connected through a band-pass filter 2, a carrier selector circuit 5 and amplifiers 3, 6 to a detector 7.
