Abstract :
In given article effects of quantization in FFT algorithms associated with representation of handled numbers and coefficients with the limited accuracy are considered. Noise of a rounding off concern to such effects at truncation of results of multiplications, errors of scaling of intermediate results with the purpose of elimination possible overflowing, and also the errors of transformation connected to final accuracy of representation of factors
