| 1. A method for a multi-point digital wavelet generator, comprising:
storing each of a plurality of digitized data points of a high-resolution wavelet basis in one of a plurality of rows of a
memory;
determining skipped rows and non-skipped rows of the plurality of rows of the memory based upon an address skip interval;
retrieving digitized data points from each non-skipped row of the memory; and
processing the retrieved digitized data points from each non-skipped row in accordance with a clock frequency to generate
an analog wavelet basis, wherein a duration of the analog wavelet basis is determined based at least in part upon the address
skip interval and the clock frequency.
