Block diagram of the DDC and corresponding frequency response. The interpolation and decimation filtering of a DUC and DDC is typically done in multiple stages using multiple filters. For example, a ...

The next step is to smooth the upsampled data sequence via an interpolation filter. The process is illustrated in Figure 12-5a. Figure 12-5A. Block diagram for the upsampling process with L = 3.
