摘要

The method involves storing each of digitized data points of a high-resolution wavelet basis in a set of rows of a memory e.g. RAM or ROM. Skipped and non-skipped rows of the set of rows are determined based on an address skip interval, and the digitized data points are retrieved by a digital-to-analog converter (DAC) from each non-skipped row. The retrieved data points are processed by the converter based on a clock frequency to generate an analog wavelet basis, where duration of the analog wavelet basis is determined based on the interval and the frequency. Independent claims are also included for the following: (1) a method for a multi-rate digital wavelet generator (2) a multi-rate digital wavelet generator comprising a memory.
