(8.D.2.2 ) ZeroPadding

Overview

Zero padding

Discussion

The zero_padding_module extends the length of a block of adding zeros at the end. The module works with real or complex data and any number of channels. At instantiation time, you specify the output block size (OUTLEN). If OUTLEN is less than the input block size then the input data is truncated to OUTLEN.
