Method for temporal inversion of a wave

摘要

According to the invention, a wave, corresponding to a signal s(t) may be temporally inverted by application of a first transformation to lower the central frequency thereof to produce a first set of transformed signals Ki(t) then a second set of transformed signals K'i(t) is produced representing the temporal inversion signal s(-t) and a third transformation is applied to said second set to generate the temporally-inverted signal s(-t)
