As shown in the picture, I made a function generator to generate a sine wave with a bias of 0 and an amplitude of 2V.
Two resistors are added externally to provide a 10V bias.
I thought that adding th
This video uses animation to explain the concepts of oscilloscope triggering, storage depth, sampling rate, etc. Although this video is not perfect, for example, when it first talks about triggering,
