For flow measurement it is necessary to determine the current ... This noise/glitch filter is a digital filter that allows pulses of valid length to pass through and blocks all other pulses. This ...

Charlotte Nawijn, Ph.D. candidate at the University of Twente, has developed a new technique to improve ultrasound images of blood flow. Using a smart ultrasound pulse train, she reduced noise in ...

The researchers found that the pulses generated by both the skin and kidney cells are partly driven by the flow of calcium ions and have about the same voltage as a nerve cell zap. But the spikes ...
