WebMay 15, 2024 · Nevertheless, research works on the optical SSB generation via IQ-MZM are mainly focused on push–pull mode, whereas rare relevant results for the push–push mode [19]. On the other hand, the signal-to-signal beating interference (SSBI) is an important limitation for the performance of such systems. In acoustics, a beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies. With tuning instruments that can produce sustained tones, beats can be readily recognized. Tuning two … See more This phenomenon is best known in acoustics or music, though it can be found in any linear system: "According to the law of superposition, two tones sounding simultaneously are superimposed in a very simple way: one … See more Musicians commonly use interference beats objectively to check tuning at the unison, perfect fifth, or other simple harmonic intervals.
