Abstract
A method for processing a signal in a CSD filter includes the steps of obtaining real coefficients optimized to desired filter characteristics, calculating scaling factors for each real coefficient which minimizes errors between the real coefficients and converted CSD codes, producing optimum CSD coefficients by using the calculated scaling factors, and filtering input data by using the optimum CSD coefficients. In the method of the present invention, conversion of the real coefficients into the CSD coefficients is performed in the time domain, thereby improving operating speed and increasing bit resolution with the number of non-zero digits fixed, as compared to conversion in the frequency domain. As a result, the present invention can be applied to an adaptive filter and a polyphase filter.
