yes that is a second type of ambiguity, and it does occur in audio as well: an lower frequenncy sinusoidally amplitude modulated higher frequency sinusoid can be indistinguishable from 2 constant amplitude sinusoids at the sum and difference of the frequencies. see an article by Plomp and Leveldt for the determination of the bandwidth of the auditory frequency bins (or filter bank) |
