Abstract

1,103,449. Colour television transmission circuits; phase correction circuits. SIEMENS A.G. 25 Feb., 1965 [26 Feb., 1964], No. 8105/ 65. Addition to 1,094,307. Headings H3T and H4F. The phase-correction arrangement claimed in Claim 2 of Specification 1,094,307 is modified in that the level-dependent amplifier in the second channel is replaced by a level dependent attenuator network. The description is otherwise substantially identical with that given in Specification 1,094,307 with reference to Fig. 2.
