Jitter noise modeling and its removal using recursive least squares in shape from focus systems [PDF]

open access: yesScientific Reports, 2022
Three-dimensional shape recovery from the set of 2D images has many applications in computer vision and related fields. Passive techniques of 3D shape recovery utilize a single view point and one of these techniques is Shape from Focus or SFF.

The Relationships between Emission Geometry and Jitter Noise in Millisecond Pulsars [PDF]

open access: goldThe Astrophysical Journal
The relationships between several parameters of an emission geometry and jitter noise in 17 millisecond pulsars (MSPs) are investigated. By assuming the jitter noise is due only to a pulse variation in phase, the former can be modeled as changes in the ...

Clock jitter estimation in noise

open access: green2011 IEEE International Symposium of Circuits and Systems (ISCAS), 2011
Clock timing jitter refers to random perturbations in the sampling time in analog-to-digital converters (ADCs). The perturbations are caused by circuit imperfections in the sampling clock. This paper analyzes the effect of sampling clock jitter on the acquired samples in the midst of quantization noise and random Gaussian noise.

Amplitude Noise and Timing Jitter Characterization of a High-Power Mode-Locked Integrated External-Cavity Surface Emitting Laser [PDF]

open access: goldIEEE Photonics Journal, 2014
We present a timing jitter and amplitude noise characterization of a high-power mode-locked integrated external-cavity surface emitting laser (MIXSEL). In the MIXSEL, the semiconductor saturable absorber of a SESAM is integrated into the structure of a ...

LISA telescope: phase noise due to pointing jitter [PDF]

open access: greenClassical and Quantum Gravity, 2019
In a space based gravitational wave antenna like LISA, involving long light paths linking distant emitter/receiver spacecrafts, signal detection amounts to measuring the light-distance variationsthrough a phase change at the receiver. This is why spurious phase fluctuations due to various mechanical/thermal effects must be carefully studied.

Contribution of Jitter and Phase Noise to the Precision of Sinusoidal Amplitude Estimation Using Coherent Sampling [PDF]

open access: goldSci
Estimating the amplitude of a sinewave from a set of data points is a common procedure in various applications. This is typically achieved using a least squares method that provides closed-form estimators. The sampling process itself is often affected by
