Abstract : The effect of the presence of harmonics on frequency discrimination is measured as a function of the frequency of the fundamental component of the signal. For signals of fundamental frequency greater than approximately 2000 cps, harmonic components have little or no effect on the ability of observers to discriminate differences in frequency. Below approximately 2000 cps, however, differences in the frequency of signals containing harmonically related components are more readily discriminated than differences in the frequency of sinusoidal signals. These findings relate to the dependence of frequency discriminability on frequency. (Author)
