Abstract

A decoder. The decoder includes interpolation circuitry that receives the digital signal and interpolates the digital signal to produce an interpolated digital signal. Additionally, the decoder includes a D/A converter that is coupled to the interpolation circuitry. The D/A converter receives the interpolated digital signal and converts such a signal to an analog signal. The decoder also includes an analog mixer coupled to the D/A converter. The analog mixer receives the analog signal and upconverts the analog signal.
