Timing Jitter and Power Spectral Density of Random Walk Noise in VCO
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2008Random walk noise is an important component in the output phase noise of a voltage-controlled oscillator (VCO). The relation between this non-stationary noise component and the induced timing jitter is critical for VCO performance characterization. Rigorous derivation of the relation is provided in this paper, which corrects the error in the relation ...

2017 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics (WASPAA), 2017
Noise reduction algorithms for head-mounted assistive listening devices are crucial to improve speech quality and intelligibility in background noise. For binaural hearing devices with one microphone per device, the noise power spectral density (PSD) is commonly estimated using various assumptions about the acoustic scenario.

Mathematical Preliminaries: Power Spectral Densities of Random Data and Noise
1995In this chapter techniques for determining the power spectral density (PSD) of random data and random signals derived from the data will be presented. There exists a complete theory for determining the spectral content of random signals [1 2 3 4].

Computation of the Average and Harmonic Noise Power-Spectral Density in Switched-Capacitor Circuits
IEEE Transactions on Circuits and Systems I: Regular Papers, 2004Switched-capacitor (SC) circuits are periodically time-varying circuits and the noise at the output of these circuits is cyclostationary. This noise is therefore characterized by the average and harmonic spectral densities. We extend the method proposed in a previous paper to compute the average and harmonic noise-spectral densities in periodically ...

Low-complexity noise power spectral density estimation for harsh automobile environments
2014 14th International Workshop on Acoustic Signal Enhancement (IWAENC), 2014In this paper a simple yet robust noise power spectral density estimation algorithm is presented. The motivation for the algorithm developed here is the harsh noise environment present in automobiles along with the need to keep the complexity low for real-time implementations.

A new method of measuring the scattered light to determine the noise spectral power density is described The technique is shown to be useful at the high spatial frequencies used in holography, beyond the range of the former methods of noise power measurement.
