Dfilter Windows Interface
↓ To start Dfilter
Simwin — Dfilter Tool
The Dfilter function provides a mechanism for converting one
data file format to another. This conversion includes
transferring text or binary data into the SIM format, and
converting one SIM format to another.
Dfilter reads and writes both data of fixed point precision (up to
32 bits in wordlength), and double precision floating point data.
When writing fixed point data Dfilter will truncate the least
significant bits of the data word. The input and output of all
fixed point data used by Dfilter is written as 2's complement
integers.
When reading floating point data Dfilter returns a warning
message if an attempt is made to write +1.0 as a 2’s
complement number. If Dfilter is forced to read data outside
the range of 2’s complement numbers, it will saturate the data,
clipping the data outside of the valid range.
• Select Dfilter on the Simwin function menu.
