Normalized time domain histograms and waveforms of car noise and transmission channel noise. Left: normalized time domain histograms and waveforms of car noise; right: normalized time domain histograms and waveforms of transmission channel noise applied to 16 bit speech samples with underlying natural-binary bit mapping. The SNR values were calculated by means of a fixed speech signal level of −26 dBov and respective noise signal levels, both measured according to ITU-T P.56 [37].
