SIMULATION OF ERRORS IN FLOATING-POINT DSP CALCULATIONS
Abstract
Quantization errors like ADC errors and roundoff errors are similar in the sense that they are difficult to analyze and predict, and therefore need careful tests/measurements. This paper discusses the possibilities of the simulation of single-precision floating-point roundoff errors. It illustrates the examination of the error and discusses it in one of the most common signal processing procedures, the fast Fourier Transform. It shows a case when spurious spectral peaks appear due to roundoff error.
