Abstract:
The present invention relates to audio coding systems which make use of a harmonic transposition method for high frequency reconstruction (HFR). A system and a method for generating a high frequency component of a signal from a low frequency component of the signal is described. The system comprises an analysis filter bank providing a plurality of analysis subband signals of the low frequency component of the signal. It also comprises a non-linear processing unit to generate a synthesis subband signal with a synthesis frequency by modifying the phase of a first and a second of the plurality of analysis subband signals and by combining the phase-modified analysis subband signals. Finally, it comprises a synthesis filter bank for generating the high frequency component of the signal from the synthesis subband signal.

Claim (Index 2):
The system according to  claim 1 , wherein\n the analysis filter bank has N analysis subbands at an essentially constant subband spacing of \u0394\u03c9; an analysis subband is associated with an analysis subband index n, with n \u2208 {1, . . . , N}; the synthesis filter bank has a synthesis subband; the synthesis subband is associated with a synthesis subband index n; and the synthesis subband and the analysis subband with index n each comprise frequency ranges which relate to each other through a factor T.
