AB  - The method of noise shaping consisting in minimization of quantization noise in neighborhood of harmonics of digital test sinusoidal signal is considered. This method provides quantization noise power on harmonics frequencies considerably smaller, than methods of noise shaping with uniform power spectral density. For example for 16 bit, 44100 Hz sampling frequency, -60 dB level, 1378 Hz test signal this method provides total harmonic distortion (THD) 0.00067% (without noise shaping THD=1.1%, with dither in a frequency band (20000-22050) Hz and a standard deviation 0.46 quantum THD=0.043%). This method can be applied to measurement of nonlinearity of various systems (especially it is actual for DACs, digital filters and so on).
