Title: Improvements relating to stereophonic sound transmission systems
Inventor: PERCIVAL WILLIAM SPENCER
IPC: H04S1/00
Filed: 1957-06-11
Abstract: 890,832. Binaural systems. ELECTRIC MUSICAL INDUSTRIES Ltd. June 5, 1958 [June 11, 1957; March 11, 1958], Nos. 18333/57 and 7737/58. Class 40 (4). In a stereophonic sound transmission system of the type described in Specification 871,992, in which a control signal representative of the directional significance of sounds is derivedfrom the signals produced by right- and lefthand microphones and is used to control the gain of the reproducing amplifiers, the means for deriving the control signal exaggerates differences between the left- and right-hand signals in order to increase the angular spread of the sound images produced. As in the Specification referred to above, the left- and right-hand signals VL and VR are amplified by respective amplifiers (not shown) having gain proportional to frequency and the derived signals V<SP>1</SP>L and V<SP>1</SP>R pass to respective phase splitters. Two methods of producing the required exaggeration of differences in the signals are described in the first, of which the outputs of the phase splitters are applied in push-pull via transformers 22 and 26, respectively, of Fig. 2 to the double diode full waverectifiers 21 and 25, the low-pass filters 23 and 27 providing the required smoothing. A similar low-pass filter 29 constitutes a common return impedance for the two rectifiers. Consequently, if V<SP>1</SP>L increases, the increased potential drop across filter 29 causes its upper terminal to become more negative with respect to the point of fixed potential 31, so that the. potential applied across the double diode 25 is decreased, causing a corresponding decrease in the output V<SP>11</SP>R. The difference between the outputs V<SP>11</SP>L and V<SP>11</SP>R thus exceeds that between the inputs V<SP>1</SP>L and V<SP>1</SP>R. In the second arrangement (Fig. 3), the signals V<SP>1</SP>L and V<SP>1</SP>R are applied each to two rectifiers 18a, 18b and 19a, 19b, respectively, the second rectifier of each pair producing an output which is the negative of that of the first. The outputs of the second rectifiers 18b, 19b are applied to attenuators 36, 37 which deliver desired fractions of their outputs to delay networks 38, 39 and thence to summing amplifiers 41, 40, respectively, so that the delayed fraction of the output of 18b is added to the output of 19a, and the delayed fraction of that of 19b is added to that of 18a, with the desired result. In each arrangement the output signals V<SP>11</SP>L and V<SP>11</SP>R are applied to a coding circuit to produce the control signal of the form log V<SP>11</SP>L/(V<SP>11</SP>R+ V<SP>11</SP>L).
