Hello,
I am having a filter coefficient say [0.1629 0.5055 0.4461 -0.0198 -0.1323 0.0218 0.0233 -0.0075].
I need to implement this filter in a FPGA (Virtex-4 ML402 Xtreme DSP Edition) and for that I need to convert these filter coefficients in floating data type. Please tell me how to perform this conversion in MATLAB.
Thanks in advance

Hi Vivek,
You can either create a dfilt object using these coefficients and then change the Arithmetic property, see
doc dfilt
or you can manually convert them using double, single or fi, see
doc double
doc single
doc fi
