Sample rate converter

1. Field of the Invention A converter or a resampler used in a digital communication system converts a first digital signal representing an analog signal into a second digital signal representing the same analog signal. The converter includes a converter filter and a timing circuit. The timing circuit provides a first clock generated from a second clock, and a phase control signal for controlling the conversion of the converter filter. The timing circuit is preferably a numerical controlled oscillator (NCO) and includes an accumulator for generating the first clock from the second clock and a phase offset, and a phase calculator which receives the phase offset to generate a phase control signal. The phase control signal includes a plurality of phase weighting signals, a plurality of control signals, and an interpolation signal. The first digital signal is selectively convoluted with the phase weighting signals, which is controlled by the control signals. The convoluted signals are interpolated by the interpolation signal to generate the second digital signal.
