Kev siv fais fab tsis lees txais piv qhia
Lub hwj huam ripple tsis lees txais qib (PSRR) yog qhov sib piv ntawm cov fais fab nkag rau qhov sib txawv (hauv volts) mus rau qhov tso zis hluav taws xob hloov pauv (hauv volts), feem ntau yog qhia hauv qhov ntsuas suab. Rau qhov zoo hloov pauv D / A, thaum lub zog hluav taws xob siv los ntawm kev hloov mus rau kev hloov kho thiab kev hloov pauv ntawm cov tshuab hluav taws xob, cov zis hluav taws xob tau tsawg heev. Feem ntau qhov sib piv ntawm qhov feem pua ntawm qhov puv hluav taws xob hloov mus rau qhov feem pua ntawm lub hwj huam hluav taws xob hloov hluav taws xob tau hu ua qhov fais fab sib kis tsis txaus.
