WebApr 8, 2024 · It can be observed from Fig. 5 which represents a traditional threshold-based method, that during power swing, wavelet energy amplitude of swing as well as noisy neighboring peak both cross the swing threshold value, thus detecting swing twice (green color) due to the presence of noise in signal in this duration. Weblevel. The other pattern is a clock signal with equal charge/discharge times and a more consistent, although smaller, amplitude. As you can see, the fall time of the bus signal starting at the higher voltage (red) is longer than that of the clock pulse (blue), and the red signal can’t discharge to as low a voltage during the single low bit.
