Abstract
Systems, methods, and devices are described herein for detecting abnormalities within a system based on signal fingerprinting. A plurality of electrical signals are concurrently received from a transceiver over a time period. The time period is partitioned into a plurality of sampling windows. An electrical signal of the plurality of electrical signals is sequentially selected. For the sequentially selected electrical signal, a temporal snapshot of said electrical signal is iteratively captured over a sampling window of the plurality of sampling windows. This iterative capturing is repeated for remaining sampling windows of the plurality of sampling windows. Each captured temporal snapshot is temporally concatenated over the time period according to its respective temporal position of the time period to generate the signal fingerprint.
