Multi-channel single eigenvalue
Thread Content
Teacher, may I ask: What do the terms “multi-channel single eigenvalue” and “single-channel multi-eigenvalue” refer to in the context of condition monitoring for large rotating machinery? Thank you
My understanding is the literal meaning
Multiple channels refer to multiple measurement points, while a single eigenvalue represents the common frequency vibration data of those multiple measurement points. Single-channel means one measurement point, while multiple feature values refer to various data such as twice, half, and GAP voltage of that point.
