High frequency ripple
Web6 de jul. de 2024 · High frequency oscillations (HFO) are known as markers of epileptic areas in intracranial EEG and possibly scalp EEG. We compared distributions of HFO in the ripple band (80–250 Hz) in intracranial and scalp EEG with either a conventional 10–20-montage (10–20-EEG) or a high density recording using 128 electrodes (HD-EEG). HFO … Web30 de jun. de 2024 · Integrated High- and Low-Frequency Current Ripple Suppressions in a Single-Phase Onboard Charger for EVs Abstract: Current ripples produced in single …

Web5 de out. de 2014 · Passband ripple does indicate that there will be some level of distortion in the signal -- the question is whether the level of distortion is acceptable. If maximum passband ripple is 0.1dB and signal-to-noise ratio is good, the ripple may not make a difference. But if zero passband ripple is required, then you need a Butterworth filter.
