Abstract
A Doppler audio dealiasing system has a zero inserter that inserts zeros between input samples of signal. The resultant signal is then processed in various ways. After the zeros are inserted and a new signal is formed, the newly formed signal is filtered and otherwise processed to remove inappropriate parts.
