Converting a Double Array into an Array of 16 bit integers

[Marvin9]

Need to convert an array of 1024 element double numbers into an array of 16 bit integers in RT. This array of 16 bit integers will be read or used as a Look-up table in FPGA.

Note: This function will work on either a scalar or an array.

Hi Paul,

The list is of 1024 element double array that makes a waveform (first 4 are shown below). If I directly convert it to 16 bit word integer it rounds it to nearest integer.

0

0.00390625

0.0078125

0.0117187

.......

I want to convert it to a list of integers (may be scaled) that would give me a waveform that ranges from 32767 to -32767.

Thanks.

Just some simple mathematics:

Run it through "Normalize Waveform.vi" and multiply by 32767
