Characteristics of Instrumentation An instrument is a device that transforms a physical variable of interest (the measurand) into a form that is suitable.

Pitch and Amplitude Perturbation (Jitter and Shimmer) Basic idea: Phonated speech is called quasiperiodic, with quasi being Latin for “sort of” or “more-or-less.
