Abstract

PURPOSE:To perform the coding in an extremely simple and effective way, by giving an inverting process to each element between the signal data having a weak correlation based on the rules different from each other and obtaining the general sum of the elements to compress the data. CONSTITUTION:The aural signal supplied through a microphone is fed to an A/D converter 2 through an LPF1 to be sampled and then fed to a differential circuit 3 in the form of binary digital data. The data of each one second of the signal data series are divided into data trains A, B, C and D. These data trains are led to an adder/subtractor circuit 4 to receive the inverting process based on each rule defined according to each train and then supplied to other signal data trains. The sum signal data train S comprising the general sum data obtained through the addition and subtraction carried out over the data trains A-D is stored in a storage device 6 after compression by a storage device 5 and the circuit 4.
