Medical Definition of SPECTROMETER. 1. : an instrument used for measuring wavelengths of light spectra. 2. â specÂ·troÂ·metÂ·ric \Ëspek-trÉ-Ëme-trik\ adjective.
It is important to denote the proband, so that the relationship to other individuals can be seen and patterns established. In most cases, the proband is the first affected family member who seeks medical attention for a genetic disorder.
Sidebands are spectral components that are the result of amplitude or frequency modulation. The frequency spacing of the sidebands is equal to the modulating frequency, and this fact is used in diagnosing machine problems by examining sideband families in the vibration spectrum. For instance, a defective gear will exhibit sidebands at the gear rpm around the gear mesh frequency.
