Title: System and method for coding an input signal
IPC: G10L13/06
Filed: 1976-05-21
Abstract: 1528344 Signal analysers GEN RAD Inc TIME DATA DIVISION 21 May 1976 [23 May 1975] 21202/76 Heading H4R [Also in Division G1] A signal, particularly speech, is encoded by extracting the characteristics of the poles or complex conjugate pole pairs of the Laplace transform of the signal. In a vocoder, the speech is A/D converted and 1000 successive samples grouped into a frame. The frame is converted by Laplace transform technique and the poles of the transfer function determined. The characteristics i.e. the damping factor, resonance frequency, amplitude and relative phase angle, of those poles whose energy exceeds a threshold or which are highest in rank on an energy basis are coded for transmission or storage. In the synthesizer, the speech is reconstituted either by inverse Laplace transformation or by the generation in a recursive filter of sine and exponential functions corresponding to the poles. No attempt is made to distinguish between voiced and unvoiced speech since the the pole characteristics convey adequate information. The Laplace transform is effected by a word-wired or programmed computer which may take a Fourier transform and modify its peaks to derive the Laplace equivalent. The energy of the poles is determined as the ratio of the square of the amplitude to the damping factor and the energy levels are compared to form a ranked sequence of which a predetermined number, e.g. 16 per frame, of the highest energies are utilized. The pole characteristics may be determined in two passes, the second being finer and requiring less computation. In the analyser of Fig. 3 (not shown), the digital speech samples are multiplied (35) by a sine function and passed to a fast Fourier transformer (45) and on via a store (53) to a circuit which measures the damping factor and amplitude of the poles by which to evaluate the energy as above. The product from the multiplier (35) is multiplied once more by the sine function, Fourier-transformed and fed to a peak detector (49) to convert to the Laplace equivalent as above. The frames may overlap to effect smoothing, and are dealt with by respective synthesizer arrangements whose outputs are summed.

Title: Electronic computer apparatus
IPC: H03M11/18
Filed: 1973-05-07
Abstract: 1427806 Data processing systems SONY CORP 7 May 1973 [9 May 1972 (2)] 21594/73 Heading G4A A computer comprises a number of functional units formed as integrated circuits on respective semi-conductor wafers. A keyboard (2) provides key signals K to select a functional unit via a common key bus (11, Figs. 1 and 3, not shown). Each functional unit (1, 6, 7) includes a decoder which determines whether the key signal relates to that unit and whether that unit is to receive the next key signal. If the decoder determines that this is so a key signal suppression signal KS is generated by the selected unit and passed over a common key suppression bus to prevent all the other units from responding to that next key signal. Each functional unit can provide an instruction signal I over a common instruction bus (17) to an arithmetic unit (4) to cause it to perform an arithmetic operation. Also, each functional unit can supply an instruction suppression signal IS over a common bus (29). The selected functional unit generates an IS signal when it occupies the arithmetic unit for an arithmetic operation. The IS signal is passed to the non- selected units to prevent them from generating an IS signal and from occupying the arithmetic unit. The functional units and the arithmetic unit are connected by a common data bus (21). Functional units may be added to the computer merely by connecting them to the various common lines. When a functional unit receives a key signal K it generates a demand signal C1 if it is to respond to the next signal K, a refusal signal if it is not to respond to the next signal K, and a receipt signal C3 if the signal K is pertinent to that unit. An instruction signal generated by the selected functional unit causes generation of a self-selection signal SS if the instruction is for the selected unit, or an other selection signal OS if it is for another unit. If the unit has generated a demand signal C 1 it delivers key suppression signal KS to the common key bus (11) so that only this unit receives the next key signal.
