Claim 2:
3. A method for generating a high frequency component of a signal from a low frequency component of the signal, the method comprising:
providing a set of analysis subband signals from the low frequency component of the signal; wherein the set of analysis subband signals comprises at least two analysis subband signals;
determining a set of synthesis subband signals from the set of analysis subband signals, such that an nth synthesis subband signal of the set of synthesis subband signals is determined from a kth analysis subband signal and a (k+1)th analysis subband signal of the set of analysis subband signals; wherein both a magnitude and a phase of the nth synthesis subband signal are determined based on a transposition order T; and
generating the high frequency component of the signal based on the set of synthesis subband signals.
