Metrologia: Pomiar szumów i tętnień zasilaczy impulsowych i liniowych. Piotr Burnos

Noise and ripple are an indicator of the quality of DC power supplies. However, correctly measuring low-level voltages is challenging. This is especially true for measuring the ripple and noise of the output voltage of switching and linear power supplies. In this video, I discuss how to perform such a measurement correctly and how to avoid errors. Join me, Piotr Burnos. Do you appreciate my work and want to support me?
