Hi,



We here are using Intell IPP platform.

In volume 1 :signal processing -> filtreing functions -> filtering functions -> filtering functions -> FIR Filter Coefficient Generating Functions -> FIRGenLowpass

there is an example given. In this example the values generated by ippsFIRGenLowpass_64f(rFreq, taps, tapslen, ippWinBartlett, ippTrue); lookes strange to me because they are very high values. But to me information these coefficient must in a range of [0,1).



Can you pleases check and verify it.

Hi,

What is the very high value you got? When I run the sample, I found the following taps value?

-0.000000 -0.021455 0.000000 0.150183 0.371272 0.371272 0.150183 0.000000 -0.021455 -0.000000.....

These value looks fine.

Thanks,
Chao
