The UPDRS scale has been modified over the years by several medical organizations, and continues to be one of the bases of treatment and research in PD clinics.
Figure 3. SFDR is a ratio of the signal fundamental frequency amplitude to the maximum amplitude of spurs or noise. Instruments with high SFDR can measure or generate a signal with high fidelity. An instrument that has very low noise and device spurs is said to have very high dynamic range or a very low noise floor. This means that a device with high SFDR can measure or generate a signal with very few effects from noise and spurs. Back to Top. 4. Signal-to-Noise Ratio
