If sampling frequency is at least one order of magnitude higher than the frequency of measured signal, we are talking about oversampling method.
For example, regarding the measurement of the physical activity level, avoiding frequencies over 5 Hz when the sampling frequency is 30 Hz could overestimate the level of physical activity (21).
But a single voltage vector is only used in a control cycle, so it needs very high sampling frequency to get good performance [18].
The reference data as in Figure 13 have 10 seconds of recording with a sampling frequency of 250 Hz, obtaining in total 2500 samples representing instants t.
Considering these characteristics, OperaBLE is a combination of low-frequency and low-cost prototyping board for developing algorithms based on adaptability, low power operation, and sampling frequency.
The table describes the audio dataset for same sampling frequency of about 48 kHz with duration of 1 min and less than 1 min.
Five impact tests of one minute length, using a combination of short and long intervals between hits, were performed for each testing location using a sampling frequency of 400 Hz.
In all simulations, the following parameters will be used: the sampling frequency [f.sub.s] = 100 kHz and the acquisition time T = 1 sec, so the number of samples N = 100000, discrete Fourier transform (DFT) computed with a 100000point FFT, and the frequency increment df = 1 Hz.
The ADC must be compacted, fast at a sampling frequency (100 MS/s), very low power dissipation, and responsive to a minimum signal of approximately 7.81 mV.
The dead angle discriminance and the waveform symmetry discriminance have high requirements on the sampling frequency and are subject to the saturation of the current transformer.
