Instantaneous FrequencyEnsemble Empirical Mode Decomposition (EEMD)To investigate the value of decomposed short-time digital volume pulse (DVP) signals in discerning systemic vascular anomaly in diabetic patient
where Re{z(t)} represents the real part of the complex signal z(t). To ensure that the instantaneous frequency obtained from Eq. (15) is physically meaningful, the instantaneous phase θ(t) must be a mono-component function (i.e., a single-valued function over time). As shown in (1...
Frequency modulation(FM): the form of modulation in which the frequency of the carrier is varied in accordance with theinstantaneousvalue of the modulating signal. 频率调制:载波的频率依照调校讯号的瞬时值而改变的一种调制。 属类:行业术语-印刷- ...

The instrument has the function of removing the disturbance of the power–frequency on the electrophysiological signals. In the international standard 10–20 EEG electrode place- ment system (Okamoto et al. 2004), 15 electrodes that are most relevant to the MWL variations were selected, namely F3...
The 3550 and 3551 take measurements from the battery terminals, and can therefore function with completely sealed batteries. Relationship between charging time and charge capacity or internal resistance The operational life of a battery depends on the frequency of use (number of charge/discharge cycles...

The RF (radio frequency) circuitry108receives and sends RF signals, also called electromagnetic signals. The RF circuitry108converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. The RF circuitr...
