The analysis performed shows that the parameters of the two groups are uncorrelated and independent, and some variants of jitter and shimmer did not follow normal distribution for PD patients. WebThe maximum theoretical quantization noise (shimmer and jitter) for digital recording systems is estimated and compared with normal vocal shimmer and jitter. Nine bits of resolution and 500 samples per cycle are needed to minimize the contaminating sampling noise without interpolation between sample …
