Abstract

1,062,269. Band-pass filters. COMPAGNIE FRANCAISE THOMSON-HOUSTONHOTCHKISS BRANDT. Dec. 19, 1963 [Dec. 19, 1962], No. 50179/63. Heading H3U. A band-pass filter having a steep-sided passband characteristic and a substantially linear relation between phase-shift and frequency comprises a plurality of series-resonant circuits 3 1 -3 n each having substantially the same bandwidth and being successively spaced in frequency by the amount of said bandwidth and each being connected in series with a respective phase-shift network 4 1 -4 n , the phaseshifts introduced thereby successively increasing by #/2, the series combinations of resonant circuit and phase-shift network being all connected in parallel between input and output distribution networks 2 and 5.
