WebJan 13, 2024 · The chokes form a low-pass filter that filters away EMI and noise which is normally very high in frequency. The reason for the ferrite core is that the ferrite increases the inductance of the choke as compared to an air-core coil/choke. More inductance = lower cut-off frequency = less noise /U. >>DIY Projects Blog<< WebChoke ALL input cables into the radio room. This means, all AC cables, all phone lines, all computer cables.
