(Q1) What sort of differences do you obtain? (Q2) Do these differences make sense? Now, look at the response of the circuit to an input square wave of low frequency (~1 kHz). If you examine the spikes in detail (e.g. using 50 usj'div), you should be able to see an exponentially damped sinusoid this is ringing. (Q3) Manually draw the ringing displayed on the scope including time and voltage scales
