Abstract (en)
[origin: EP0046266A2] Method for the sum-correct distribution of an audio frequency signal to N output channels. For this purpose, exactly N-1 filters are used and at least 1 difference summing circuit which forms the complementary signal allocated to a group of filters having a common input signal. If only one difference summing circuit is used, a single-stage circuit arrangement is produced in which the audio frequency signal is distributed to N outputs within one stage. If, in contrast, more than one difference summing circuit is used, a multi-stage circuit arrangement is produced in which the audio frequency signal is distributed to N outputs in several stages. <IMAGE>
