1. A device or component that separates or isolates two systems, signals, or mechanical parts to prevent unwanted interaction or interference.
Usage: commonly used in electronics, engineering, and physics
2. In electronics, a capacitor or other component used to block direct current while allowing alternating current to pass through.
Usage: technical; electronics and signal processing

Examples

• The decoupler in the circuit prevents low-frequency noise from affecting the sensitive amplifier.
• Engineers installed a mechanical decoupler to isolate vibrations from the engine.
• A decoupler capacitor is essential for blocking DC bias in audio signal chains.
• The decoupler allows the two subsystems to operate independently without interference.
• In power distribution systems, decouple capacitors serve as decouple to stabilize voltage.
• The decoupler reduced cross-talk between adjacent transmission lines.
