Title:
FREQUENCY RECONFIGURABLE DIGITAL FILTER AND EQUALIZER USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2011/105879
Kind Code:
A2
Abstract:
A frequency reconfigurable digital filter and an equalizer using the same are disclosed. The digital filter includes a sampling kernel storage section configured to store a sampling kernel for performing upsampling of a model filter response scaled by a sampling constant and generating response of Multi images which are repeatedly formed with a constant period; a complementary conversion section configured to generate response of Multi complementary images repeatedly formed with constant period in frequency domain where the Multi images are not generated, the Multi complimentary images having the same characteristic as the Multi images; and an image response operation section configured to operate response of an image corresponding to a selected band among the Multi complementary images and the Multi images. The filter reconfigures frequency to realize various band pass characteristics only through changing very small number of parameter, and a user may change easily band of the filter.
