On Computing Dominant Frequency From Bipolar Intracardiac Electrograms
IEEE Transactions on Biomedical Engineering, 2007Dominant frequency (DF) computed from action potentials is a key parameter for investigating atrial fibrillation in animal studies and computer models. A recent clinical trial reported consistent results computing DF from 30 Hz to 400 Hz bandpass filtered bipolar electrograms in humans.

Frequencies Dominant in the Perception of the Pitch of Complex Sounds
The Journal of the Acoustical Society of America, 1967This paper deals with measurements carried out with pulsive signals to determine the spectral region associated with dominant pitch perception. The stimulus consisted of the sum of (1) a low-frequency band of a unipolar pulse train with fundamental frequency f0 (or f0+Δf) and upper cutoff frequency fe and (2) a high-frequency band of a unipolar pulse ...

Dominant frequencies in the wake of the two cylinders
AIP Conference Proceedings, 2016This article discusses the results of the spot measurement of the velocity fluctuation in the wake of two cylinders for two mutual positions and two modes of Reynolds numbers obtained using a hot wire probe (CTA method). The measurement for each setting was done at 121 points located mainly in the wake of both cylinders.

Onset dynamics of ventricular tachyarrhythmias as measured by dominant frequency
Heart Rhythm, 2011Differences in dominant frequency (DF), a measure of electrical activation rate, were used to characterize and classify ventricular tachyarrhythmias (VTA) at onset.In canine 3- to 5-day-old infarct border zone, monomorphic re-entrant ventricular tachycardia (MVT) was repeatedly induced by programmed electrical stimulation (14 experiments, total of 23 ...

Heterogeneity of dominant high‐frequency sensorineural deafness
Clinical Genetics, 1988There are several types of autosomal dominantly inherited sensorineural hearing loss (AD‐SNHL), differentiated by audiograms. It is generally accepted that there are similarities in audiograms among members of the same family with dominant deafness. It has been supposed that AD‐SNHL must be divided into several types according to their audiograms or ...

Medical Physics, 2007
Introduction: Dominant frequency(DF) can be defined as the frequency with the maximal power in a frequency spectrum. This concept has been used to analyze signals in various fields of science as diverse as music, cardiac and seismic signals. In the current study DF and related frequency analysis techniques were used to investigate the reproducibility ...

Frequencies Dominant in the Perception of Pitch of Complex Sounds
The Journal of the Acoustical Society of America, 1966In an investigation of the pitch of complex sounds, the relative importance of selected bands of frequencies was evaluated by determining the minimum sensation levels (SL) at which the bands govern over-all pitch. The stimulus consisted of the sum of (1) a low-frequency band of fundamental frequency f0 and upper cutoff frequency fc and (2) a high ...

Frequency recognition for SSVEP-BCI using reference signals with dominant stimulus frequency
2015 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA), 2015Detection of frequency for steady-state visual evoked potentials (SSVEP) is addressed. We propose to use the combination of CCA and training data-based template matching between two level of data adaptive reference signals that can deal with the dominant frequency.
