amplitude noise

amplitude noise

[′am·plə‚tüd ‚nȯiz]
(electromagnetism)
Effect on radar accuracy of the fluctuations in the amplitude of the signal returned by the target; these fluctuations are caused by any change in aspect if the target is not a point source.

The iFLEX-iRIS laser series consists of a range of solid-state, high-performance lasers with low amplitude noise.
The added amplitude noise is random Gaussian noise with a zero mean and deviations of 20%, 50% and 100%, respectively.
SSB phase noise, amplitude noise, AM noise measurement, additive or residual noise characterization, and baseband noise measurements up to 6 GHz can easily be made for sources such as crystal oscillators, PLL synthesizers, clocks, phase-locked VCOs, and DROs.
While the phase noise has been calculated by the LTV model, there is no closed formula for A-ISF and no amplitude noise has been calculated by this model [6].
The NXA is designed with a two-channel phase and amplitude noise analyzer using cross-correlation to cancel its own internal noise.
Amplitude noise can be separated into its constituent parts in the same way as timing jitter.
SSB phase noise, amplitude noise, AM noise measurement, additive or residual noise characterization, and baseband noise measurements up to 6GHz can easily be made for sources such as crystal oscillators, PLL synthesizers, clocks, phase-locked VCOs, DROs, and many others.
Employing this technology, suppression of optical amplitude noise using a 107 gigabit per second (Gbps) phase modulated ultra high-speed signal was successfully verified.
Rather than concentrating on theory, practitioner Maas emphasizes real-world circuit performance, giving some background on phase and amplitude noise as well as linear and nonlinear noise, then progressing to noise and random processes, including narrowband random processes, noise figure, noise temperature, and the system noise model, the noise theory of solid-state devices and of linear and nonlinear circuits, low-noise amplifiers, oscillators, and mixers and frequency multipliers.
For those designs that prevent saturation of the active device by using AGC techniques, the phase noise is low and the amplitude noise can be comparable.
Options are available for amplitude noise and measurement of phase and amplitude noise on pulsed signals.
Any jitter on the analog input translates to amplitude noise on the ADC's output, affecting the ADC's signal-to-noise ratio," an adverse effect that becomes increasingly critical as the frequency range of ADCs increases.
