Passive differentiator... High Pass Filter ... passive differentiator output volts shape across resistor seen here.

Thank you for sharing...👍

Thanks lenz .... Here's more info for interested users: ... Android users will see a long narrow bar at the bottom left of their scope which has its time length shown (100us at present). Those Android users can swipe a finger along their scope and so alter the time setting of that bar. If a user first enters the left pulse source settings, and there alter the 'period' to become 1ms instead of the present 100us, then the result will be better seen if they then swipe their scope to get that bar to show the same 1ms. That result seen on the top scope will show small differentiated peaks instead of showing the square pulses of the input. ...  Likewise if users alter the left pulse source period setting to be 1us, and then swipe their scope until that bar reads as 1us, then they will see that these now higher frequency pulses look similar to the original square input pulses... it's a High Pass Filter output voltage here across the RC resistor: with good similar square replicas at HF, and only insignificant small blips at LF ... Some users will have noticed that the current here displayed is identical to the shape and time of the voltage across the resistor for a RC passive differentiator. ... A Volt meter put across the resistor would show that similarity.

iOS device users also have this bar and can swipe their finger to change the time scale (I use an iPad).
