G10H 7/10

using coefficients or parameters stored in a memory, e.g. Fourier coefficients (G10H7/12 takes precedence)

Introduced: January 1990

Title

Titles differ between systems:

IPC: using coefficients or parameters stored in a memory, e.g. Fourier coefficients

CPC: using coefficients or parameters stored in a memory, e.g. Fourier coefficients (G10H7/12 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Instruments in which the tones are synthesised from a data store, e.g. computer organs > by calculating functions or polynomial approximations to evaluate amplitudes at successive sample points of a tone waveform > using coefficients or parameters stored in a memory, e.g. Fourier coefficients

CPC:

Instruments in which the tones are synthesised from a data store, e.g. computer organs > by calculating functions or polynomial approximations to evaluate amplitudes at successive sample points of a tone waveform > using coefficients or parameters stored in a memory, e.g. Fourier coefficients (G10H7/12 takes precedence)

Of 1 combined children, 0 exist in both systems.

1 codes are CPC-only extensions.
