Which type of network provides the greatest harmonic suppression?
- APi-L network
- BInverse pi-network
- CPi-network
- DL-network
Correct answer: A — Pi-L network. From the official ISED question bank, verified word for word.
Why
A Pi-L network adds an extra inductor and capacitor to the standard Pi shape, creating a steeper filter that blocks unwanted harmonic signals more effectively than simpler designs. The full explanation — and one for every question — is in Pro.
