Abstract: 1,237,646. Equalization networks. WANDEL U. GOLTERMANN. 28 April, 1969 [27 April, 1968], No. 21543/69. Heading H3U. An adjustable network for correcting both attenuation and delay time distortion in a circuit and enabling the adjustment of one correction to be made without unduly affecting the adjustment of the other correction, comprises a chain of variable partial equalizers, each equalizer being constructed according to Fig. 3 or Fig. 4. The partial equalizer of Fig. 3 comprises a transformer 34 having first, second, and third windings 31, 32, 33, respectively, the input being connected across winding 31. Winding 31 constitutes a first bridge arm and has a relative winding number "1" and windings 32, 33 constitute a second bridge arm. Winding 32 has a relative winding number n and winding 33 has taps 35 whereby the relative winding number may vary over a range in steps having the ratio u i  À (1 +n) = 10(-a 0i /20) . (1+n), where a oi  is the required attenuation value. A third bridge arm is formed by a resistor 36 adjustable in steps, and a fourth bridge arm consists of a series resonant circuit formed by an inductor 38, a variable capacitor 39 and a resistor 37 switched in steps concurrently with the resistor 36. Each step of the resistor 37 has a resistance value n times that of the resistor 36. A changeover switch 310 permits the winding 33 to be reversely connected to the winding 32 to permit the attainment of both positive and negative attenuation values. Thus attenuation distortion is corrected by adjustment of the tap 35 on the transformer winding 33 and delay distortion is corrected by adjustment of the resistors 36, 37. In the other embodiment of partial equalizer, Fig. 4, the third bridge arm consists of a parallel resonant circuit formed by a variable inductor 49, a capacitor 48 and a variable resistor 46 and the fourth bridge arm is formed by variable resistor 47.
