@PLCProf posted:I think John is talking about an L-C low-pass arrangement, with the TVS as the C. The supply to the electronics would be taken off across the TVS. So, the L protects the DCS track signal from the shunt capacitance of the TVS, but the TVS is directly across the electronics, affording maximum protection to the electronics, but less protection to the track.
So L is series with the engine board meaning the DCS waveform won't enter. That means this discussion is not for a DCS engine right? (I think this is what I was missing above).
The electronics we are talking about protecting are not DCS decoders. Right?
