The frequency domain features of the vibration signal contain a rich fault information. However, how to extract multi -dimensional features from it to achieve failure and complicated conditions is ...

Technologists and investors are pushing AI tools as a path to peace—and profits—as they navigate a minefield of risks.

If you assume the rise time to be 20% of the signal's period (0.2T=8.3 nsec), then T=41.5 nsec, and frequency=24 MHz. So, for signals with frequencies higher than 24 MHz, this cable is a transmission ...

The design of time-limited binary signals imbedded in colored Gaussian noise resulting from passing white noise through a channel of known transfer function is investigated. It is shown that, for a ...
