In the medical field, this method is used for specific diagnostic goals:
| Test Method | Speed | SNR (Signal/Noise) | Distortion detection | | :--- | :--- | :--- | :--- | | (one freq at a time) | Very Slow | Excellent | Good | | White Noise (random) | Fast | Poor | Poor | | Chirp/Sweep | Fast | Good | Medium | | Multisinusprüfung | Fast | Excellent | Excellent | multisinusprüfung
Here is the deep dive into what it entails. In the medical field, this method is used
A Multisinusprüfung is a test signal method where (sinusoidal oscillations) of different frequencies, amplitudes, and phases are summed together and applied to a Device Under Test (DUT) simultaneously. Unlike a single sine sweep (which tests one frequency at a time) or white noise (random signal), a multi-sine is deterministic and periodic. "Multisinusprüfung" is a German term that translates to
"Multisinusprüfung" is a German term that translates to or "Polysinusoidal Test."
