If you simulate circuits that include not only analog, but also digital or switching/PWM aspects, then you know that traditional “AC” or frequency-domain analysis cannot be used for these designs.
Specifications for digital oscilloscopes typically include dc accuracy, 3-dB bandwidth, rise time, and overshoot but not the instrument’s frequency response. It’s not a surprising omission, as a ...
Pinpointing the minimum and maximum transient noise bandwidth for a transient noise simulation is a non-trivial task. But ...
