Hello, I have a little problem, I need make a audio filter between 100 and 1KHz of frecuency, but designing the filter with Z transform given me float coefficients and my project don't has any FPU, my questions is, How I can design the filter that I need without make a FPU.

The audio signal has 8 bits of resolution and I must to use a LM32 SOC.

Thanks for the help.

You have to scale up the coeficients (and round to the next integer), and later on, scale down the result again. Remember divide by a power of 2 is easy. The bigger the scale factor, the more the filter will look like the one with the floating point coeficients.
