Threshold knowledge is a term in the study of higher education used to describe core concepts—or threshold concepts—which, once understood, ...
Zalo is a Vietnamese instant messaging multi-platform service developed by VNG Corporation. Zalo is also used in other countries outside of Vietnam, including the United States , Japan , South Korea , Australia , Germany , Myanmar and Singapore .
In measuring sensory threshold, noise must be accounted for. Signal noise is defined as the presence of extra, unwanted energy in the observational system which obscures the information of interest. As the measurements come closer to the absolute threshold, the variability of the noise increases, causing the threshold to be obscured. [5]
One definition of signal-to-noise ratio is the ratio of the power of a signal (meaningful input) to the power of background noise (meaningless or unwanted input): =, where P is average power.
In electrophysiology, the threshold potential is the critical level to which a membrane potential must be depolarized to initiate an action potential.
where or Vtsat is the threshold voltage measured at a supply voltage (the high drain voltage), and or Vtlin is the threshold voltage measured at a very low drain voltage, typically 0.05 V or 0.1 V. is the supply voltage (the high drain voltage) and is the low drain voltage (for a linear part of device I-V characteristics). The minus in the ...
The threshold voltage, commonly abbreviated as V th or V GS(th), of a field-effect transistor (FET) is the minimum gate-to-source voltage (V GS) that is needed to create a conducting path between the source and drain terminals. It is an important scaling factor to maintain power efficiency.
A compressor reduces the level of an audio signal if its amplitude exceeds a certain threshold. Threshold is commonly set in decibels (dBFS for digital compressors and dBu for hardware compressors), [8] where a lower threshold (e.g. −60 dB) means a larger portion of the signal is treated. When the signal level is below the threshold, no ...
