Abstract

941,205. Detector circuits. PYE Ltd. June 1, 1962 [June 2, 1961], No. 19969/61. Heading H4L. A diode detector circuit which can be switched to produce output signals in the same sense when either positive or negative modulated television signals are applied to its input comprises a diode D and capacitor C 2 connected in series across the secondary winding of I.F. transformer T, an R.F. choke L 1 , two capacitors C 3 , C 4 and a second R.F. choke L 2 connected in series across capacitor C 2 with the junction of capacitors C 3 , C 4 earthed and a pair of ganged switches S 1 , S 2 by means of which either point A is connected to earth and the detector output is obtained from point B or vice versa.
