Content:
- The schematic
- The board / circuit
- Example: Long rise time
- 2us rise time, no decoupling capacitor
- Fast rise time, no decoupling cap
- Fast rise time, moving probe
- Estimating decoupling capacitor value
- 1000uF close to circuit
- 1000uF far from the circuit
- 1uF close to the circuit
- Where to place decoupling capacitor
- 1 vs 2 capacitors
