Novel methods for improving compression efficiency by compressing and encoding images are proposed in this patent. The image to be compressed is partitioned into blocks, which will then be individually analyzed to determine suitability for discrete wavelet transform pre-processing. The blocks are al.....

High-order filters, capable of increasing the efficiency of converters, depend on advanced control algorithms to reduce multiple resonant frequencies, but that such algorithms often require precise information about the component parameters of the converter’s output filters. To capture the parameter.....
