Title: Directional enhancement system for quadraphonic decoders
Inventor: WILLCOCKS MARTIN EDMUND GEORGE
IPC: H04R3/12
Filed: 1974-03-25
Abstract: 1514162 Quadraphonic systems W RUGGLES 14 May 1975 [25 March 1974] 13047 Heading H4R In a matrix quadraphonic system the output signals of the matrix 102 at the reproducer are applied to a detector 103 to provide a plurality of direction control signals which are applied to a processor 104 which combines the direction control signals so as to provide a plurality of coefficient signals which, by matrix multiplication of the output signals of the decoding matrix 102, provide output signals in which the directivity is enhanced. As described the detector 103, shown in detail in Fig. 2, detects the relative signal levels in the decoding matrix output signals, and their combinations, to provide the direction control signals C 45 , C 180 , etc., the signals being standardized by the gain controlled amplifiers 116 to 119 and fed to comparators 164 to 173 to provide output signals only on those comparators whose signal level input is lower than the reference level derived from the combined signal level. The direction control signals are fed to a charge-discharge time constant control circuit, Fig. 7, which maintains a signal active for a predetermined hang over time after it becomes inactive, unless another signal becomes active when, by the interconnection of the outputs via transistors 315a to 315x, the signal is rapidly caused to become inactive, at least for the duration of the other signal. The direction control signals are combined in various proportions, depending on the particular matrix system in use, to provide matrix multiplier coefficients which, applied to matrix multipliers 416 to 419, Fig. 8, multiply the decoding matrix output signals L<SP>1</SP> F , R<SP>1</SP> F , R<SP>1</SP> B , L<SP>1</SP> B , to provide components which, when combined with the decoding matrix output signals, cancel cross talk components from those signals. The coefficient derivation and matrix multiplier are of such form, Figs. 11 and 12 (not shown) that the total power of the signal remains constant even though its direction appears to change. The derivation of the direction control signals and matrix multiplier coefficients is mathematically derived and described for the SQ and QS systems. (For figures see next page)
