coefficient conversion

Started by Nathaniel Gorre February 14, 2002
Hi!

I am developing an IIR filter using a C5402 DSK. Then,
I used LabView to obtain the coefficients for my
desired filter response. Since, the C5402 is a fixed
point DSP and the coefficients from LabView are in
float so conversion to signed short integer is
necessary. Am I correct if I will just multiply the
float values with 32768 to get the Q15 value?

Also, what should be done with float values greater
than 1? How will I scale them?

Thanks.

Nathaniel
