Abstract
A digital data rate enhancement filter is described. The digital data rate enhancement filter-includes an enhancement filter input, a first interpolation filter, a second interpolation filter, and a multiplexer circuit. The first interpolation filter is connected to the enhancement filter input downstream of the enhancement filter input. The second interpolation filter is connected to the first interpolation filter downstream of the first interpolation filter. The enhancement filter input is configured to receive a digital input signal set. The first interpolation filter is configured to receive the digital input signal set and to interpolate the digital input signal set, thereby obtaining a first interpolated signal set. The second interpolation filter is configured to receive the first interpolated signal set and to interpolate the first interpolated signal set, thereby obtaining a second interpolated signal set. The multiplexer circuit is configured to selectively receive the first interpolated signal set and/or the second interpolated signal set. The multiplexer circuit further is configured to output the first interpolated signal set and/or the second interpolated signal set r…
