WebApr 14, 2024 · A SAW filter produces surface acoustic waves using a piezoelectric substrate, such as quartz. A group of input and output transducers on the substrate’s surface receive an electrical signal, which causes them to create waves. The vibrating transducers produce acoustic waves due to the electrical signal and travel through the substrate. WebDec 1, 2004 · A 6-pulse rectifier will typically have about 30% THD, rich in 5 th and 7 th harmonics. A 12-pulse rectifier will have less than one-half of the THD that we see in a 6-pulse rectifier and is rich in 11 th and 13 th harmonics.
