| 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. https://youtu.be/7kFB5tGtZBY |
