Circuit Puzzle 2 (Matching Capacitors)

Sometimes a simple circuit can intensely test one’s knowledge about electronics basics. Using an Analog Arts (http://www.analogarts.com/) oscilloscope, we analyze a simple circuit which proves to be challenging.
To analyze the circuit we use two basic principles, a transition between two voltage levels has infinite frequency components, and the impedance of a capacitor approaches 0 as the rise time decreases, or the signal frequency increases.
We modify the circuit and achieve a simple setup for testing and triming capacitors with wide tolerances.
We welcome your view and appreciate your thoughts on this and similar subjects.
