Transistors or diodes "clip" the amplitude of a pulse, removing noise or ensuring it stays within logic-level boundaries.
Transistors are the building blocks for several specialized pulse-generating circuits: Transistors in Pulse Circuits
These maintain a pulse's voltage at a specific fixed level without altering its shape, often used to restore signals that have become distorted during transmission. 4. Critical Design Considerations Transistors - SparkFun Learn Transistors or diodes "clip" the amplitude of a
