Hello to all! I have created FIR filter in Matlab (FDATool), and i have simulated how the filter is working. In the first time i have used floating-point, and i have taken right result in output signal. But in the next time i have used fixed-point, and it is the result of simulation . What is it? Errors of quantization? And how i can fix it?
use floating point, relax filter constraints. But the info you provide is not sufficient to really help...
