Peak-to-peak amplitude (abbreviated p–p or PtP or PtoP) is the change between peak (highest amplitude value) and trough (lowest amplitude value, which can be negative). With appropriate circuitry, peak-to-peak amplitudes of electric oscillations can be measured by meters or by viewing the waveform on an oscilloscope .
Amplitude and duration contribute to the area's value. [ 11 ] Temporal Dispersion: It is the “range of conduction velocities of the fastest and slowest nerve fibers.” [ 11 ] The NCS waveform becomes wider with nerve stimulation toward the nerve's origin compared to further down the nerve, with the area under the waveform staying constant ...
For this reason the noise amplitude of the average of trials is expected to deviate from the mean (which is ()) by less or equal than / in 68% of the cases. In particular, the deviation wherein 68% of the noise amplitudes lie is 1 / N {\displaystyle 1/{\sqrt {N}}} times that of a single trial.
The P3b has been a prominent tool used to study cognitive processes, especially psychology research on information processing. Generally speaking, improbable events will elicit a P3b, and the less probable the event, the larger the P3b amplitude. [10] This was shown to be true both for the overall probability and for the local probability. [2]
The latency, amplitude, and distribution of the N200 are sensitive to several factors depending on the type of experiment. The N200 is often seen as part of a complex of components including the P3a and P3b. The N200 component responds functionally much like the P3b component in that stimulus probability can affect the amplitude of both. This ...
With now-extensive research, it is also possible to dissociate these components even when the experimental context is different and/or less well-studied. P3a amplitudes tend to be maximal over frontal/central sites on the scalp, such as FCz/Cz in the international 10-20 system , which is the standard electrode placement system of many ERP labs ...
In quantum mechanics, a probability amplitude is a complex number used for describing the behaviour of systems. The square of the modulus of this quantity represents a probability density . Probability amplitudes provide a relationship between the quantum state vector of a system and the results of observations of that system, a link was first ...
The modulus of the number is the amplitude of that component, and the argument is the relative phase of the wave. For example, using the Fourier transform, a sound wave, such as human speech, can be broken down into its component tones of different frequencies, each represented by a sine wave of a different amplitude and phase. The response of ...
