摘要
An offset free sinc interpolating filter includes differentiators operating at a first sampling frequency, integrators operating at a second sampling frequency and one or more coefficient multipliers. The coefficient multipliers multiply a received value with a constant coefficient value to generate an output value. The differentiators, integrators and coefficient multipliers can be operatively coupled to each other, either directly or through other components such as adders and delay elements, or by a combination of the two. In operation, an input signal is provided to the sinc interpolating filter at the first sampling frequency. The input signal is processed by the differentiators, integrators and coefficient multipliers to generate an output signal at the second sampling frequency. Once the output signal is generated, the integrators are reset before the next input cycle begins.
