In the re-sampling process (sampling rate conversion), there are two basic configurations as shown in Figure 1 and Figure 2. In Figure 1, the re-sampling is implemented by Downsampling (Decimation) factor, and then followed by Upsampling (Interpolation) factor. Meanwhile, in Figure 2, the re-sampling is implemented by Upsampling (Interpolation) factor, and then followed by Downsampling (Decimation) factor. If D = I or M = L, shows that the output of the two configurations, x' (n) as shown in Figure 1 and Figure 2 are different. x (n) x (n) D (M) ↑I(L) ↑I(L) Figure 1 ↓D (M) Figure 2 x' (n) x' (n)
