| David Sedlacek | Decimal to Quantized Decimal converter. This shows the closest possible representation for decimal number given a binary bit width. You can type 'xbit' from the command line to see the usage, but it takes the bit resolution as an argument (but can be updated after starting) and an optional value which causes the output to include the next user-given bit-resolutions. The decimals are entered as 0.498324832 or -0.2485928493 for example, and it outputs the binary equivalent and the quantized decimal equivalent to 10 places. I haven't had time to thoroughly test it, so let me know if you see anything crazy, or if you can suggest improvements to the interface. | Xbit.exe |
| Software Group | Spreadsheet Simulator for the Filter. Has some issues. See
e-mail archive for details. But still very useful. We will call this
version 1. Stay tuned for updates
Here is version 2 |
