Abstract
A frequency converter is disclosed, which improves processing time and reduces hardware costs, in converting input data sampled at a first frequency into output data compatible with a system operating at a second frequency. The frequency converter has first and second coefficient generators for calculating first and second coefficient values, respectively. The frequency converter uses an interpolator for interpolating input data using the first and second coefficient values into the output data. In addition, a dual-port memory stores the output data in accordance with the first frequency and outputs the stored data in accordance with the second frequency.
