Dear all, Happy New Year. I am designing a FIR filter i want to study the finite wordlength effects, i want to reduce the bit size for representing the coefficient, but to reduce that i want to know exactly with how many bits the coefficeint is generated in matlab. give me any idea regadring this issue, thank u. regds,sree. |

rounding off the coefficients

Use fdatool in filterdesign toolbox. You can do all kinds of finite precision effects analysis while you design the filter. Before any quantization the filter coefficients will be double precision.
