👉 In electrical engineering, an "upsweep" is a type of peak-to-peak voltage variation that occurs when an AC source exhibits a low-frequency component. This phenomenon can be observed in transformers, resonant circuits, and other devices where the high-frequency components are present at the top of the impedance curve. The term "up-sweep" refers to the high-frequency component of the voltage level that appears on the output side of a transformer or circuit as it passes through the low-pass filter. This
