## am·pli·tude

(ăm′plĭ-to͞od′, -tyo͞od′)
n.
1. Greatness of size; magnitude.
2. Fullness; copiousness.
3. Breadth or range, as of intelligence.
4. Astronomy The angular distance along the horizon from true east or west to the intersection of the vertical circle of a celestial body with the horizon.
5. Physics The maximum absolute value of a periodically varying quantity.
6. Mathematics
a. The maximum absolute value of a periodic curve measured along its vertical axis.
b. The angle made with the positive horizontal axis by the vector representation of a complex number.
7. Electronics The maximum absolute value reached by a voltage or current waveform.

[Latin amplitūdō, from amplus, large.]

## amplitude

(ˈæmplɪˌtjuːd)
n
1. greatness of extent; magnitude
2. abundance or copiousness
3. breadth or scope, as of the mind
4. (Astronomy) astronomy the angular distance along the horizon measured from true east or west to the point of intersection of the vertical circle passing through a celestial body
5. (Mathematics) maths Also called: argument (of a complex number) the angle that the vector representing the complex number makes with the positive real axis. If the point (x, y) has polar coordinates (r, θ), the amplitude of x + iy is θ, that is, arctan y/x. Compare modulus2 See also Argand diagram
6. (General Physics) physics the maximum variation from the zero or mean value of a periodically varying quantity
[C16: from Latin amplitūdō breadth, from amplus spacious]

## am•pli•tude

(ˈæm plɪˌtud, -ˌtyud)

n.
1. the state or quality of being ample, esp. as to breadth or width; largeness.
2. large or full measure; abundance.
3. mental range, scope, or capacity.
4. the absolute value of the maximum displacement from a zero value during one period of an oscillation.
5. the maximum deviation of an alternating current from its average value.
6. the arc of the horizon measured from the east or west point to the point where a vertical circle through a heavenly body would intersect the horizon.
[1540–50; < Latin amplitūdō. See ample, -i-, -tude]

## am·pli·tude

(ăm′plĭ-to͞od′)
One half the full extent of a vibration, oscillation, or wave. The amplitude of an ocean wave, for example, is the maximum height of the wave crest above the level of calm water, or the maximum depth of the wave trough below the level of calm water. The amplitude of a pendulum swinging through an angle of 90° is 45°. See more at wave.

## amplitude

A wave’s greatest displacement from equilibrium.

IP Infusion, a provider of intelligent network software for telecom and data communications services, has qualified the COLORZ[R] 100GbE Dense Wavelength Division Multiplexing (DWDM) Pulse Amplitude Modulation (PAM4) platform solution from Inphi Corporation (NYSE: IPHI), a provider of high-speed data movement interconnects, on its OcNOS(TM) network operating system, the company said.
A voltage spike below 10 % of the total pulse amplitude could be acquired when the 800 pF stray capacitance is present in the circuit.
In each run the pulse amplitude was raised until no false negatives and no false positives were recorded.
The challenge is to deal with the very high pulse amplitude and especially its extremely fast rate of rise.
Although various applications have been investigated for NLTLs, the line resistance generally attenuates the pulse amplitude, making pulses very small for a NLTL to exhibit nonlinearity.
In Figure 3, the graph of the working gap for a pulse amplitude of 2750 mV and a pulse width from 70 to 200 ns is shown.
LH pulse frequency drops, and LH pulse amplitude increases when a woman's available energy drops below a threshold of 2030 kcal/kg of lean body mass per day; For an average-sized woman who does not exercise, this translates into a minimum consumption 900-1,300 calories/day to avoid disruption of the LH pulse cycle.
Techniques for modulating UWB pulses include Pulse Position Modulation and Pulse Amplitude Modulation.
All women experienced increased vaginal pulse amplitude (VPA) and subjective sexual arousal in response to an erotic film, regardless of age or menopausal status.
