Hello,
I don't quite understand what is better in ferrite bead comapring to capacitor when it comes to suppressing the noise of a high frequency.
If I want to reduce the noise in the circuit then I can simply add a capacitor between signal net and ground.
I could use a ferrite bead for this as well - but what would I get addiitonally in this case?
Thanks,
Daniel
Ferrite beads are used to prevent interference in from or to a device. Ferrite beads are connected in series, whereas the capacitors are connected in parallel.
Ferrite beads suppress high frequency noise. Ferrite beads are used to reduce EMI or RFI.
The ferrite bead prevents the cable from acting as an antenna and receiving interference from other devices that are sources of interference, such as household appliances.
