The oscilloscope tracings shown below are circuit at R12, which is the base drive for an NPN output transistor. I have omitted some aspects of the circuit for clarity.
The TOP oscilloscope tracing (50 nS sweep) is taken at Point B (“after” R12); the BOTTOM tracing is taken at Point A (“before" R12).
Why is there a dip in the tracing made at Point B (after R12)?
Thanks. John
