Abstract

392,229. Amplifiers for television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, DOWSETT, H. M., 47, Drayton Gardens, Winchmore Hill, London, and WALKER, L. E. Q., Pattiswick Rectory, Braintree, Essex. Nov. 18, 1931, No. 32041. [Class 40 (v).] . An amplifier for television signals is so designed that its frequency-response characteristic has peaks at or about the line-scanning frequency and its harmonics. The major peak occurs at the line-scanning frequency, and the other peaks descrease in size as the order of the corresponding harmonic increases. The amplifier incorporates one or more tuned coupling circuits of high decrement and resonant at the line-scanning frequency. The tuned circuit shown is complex with, resonances at the linescanning frequency and its harmonics, and is inserted in the plate circuit of a thermionic amplifier, Fig. 3 (not shown). The oircuitmay be of the band-pass, filter type.
