Fixed Point Implementation of Raised Cosine Filter and CIC interpolation

[david uang]

Hi,

   I have got two questions:
   I have Digtial Filter Design Tookit 7.5 at hand with Labview 8.0.
   1. I know the design kit can generate float-point filter, is there any way I can generate a fixed point Raised Cosine filter in Laview code?
   2. If I want to generate a fixed point interpolation filter, say, upsampling M and do CIC interpolation, it there anyway to do so?
   Many Thanks.

David

Hi,

The Digital Filter Design Toolkit 7.5 does not support fixed-point multirate filter. However, the latest version of the toolkit does support that. Both of your issues can be solved by Digital Filter Design Toolkit 8.2.
