1Phase vocoder — A phase vocoder is a type of vocoder which can scale both the frequency and time domains of audio signals by using phase information. The computer algorithm allows frequency domain modifications to a digital sound file (typically time… …
2Phase dispersion minimization — (PDM) is a data analysis technique that searches for periodic components of a time series data set. It is useful for data sets with gaps, non sinusoidal variations, poor time coverage or other problems that would make Fourier techniques unusable …
3analysis — /euh nal euh sis/, n., pl. analyses / seez /. 1. the separating of any material or abstract entity into its constituent elements (opposed to synthesis). 2. this process as a method of studying the nature of something or of determining its… …
4Data analysis — Analysis of data is a process of inspecting, cleaning, transforming, and modeling data with the goal of highlighting useful information, suggesting conclusions, and supporting decision making. Data analysis has multiple facets and approaches,… …
5Phase-shift keying — Passband modulation v · d · e Analog modulation AM · …
6Phase I Environmental Site Assessment — A Phase I Environmental Site Assessment is a report prepared for a real estate holding which identifies potential or existing environmental contamination liabilities. The analysis, often called a Phase I ESA, typically addresses both the… …
7Phase-locked loop — PLL redirects here. For other uses, see PLL (disambiguation). A phase locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is related to the phase of an input reference signal. It is an electronic… …
8Phase response curve — A phase response curve (PRC) illustrates the transient change in the cycle period of an oscillation induced by a perturbation as a function of the phase at which it is received. PRCs are used in various fields; examples of biological oscillations …
9Phase Dispersion Minimization — PDM2 analysis for the double mode Cepheid variable TU Cas, primary period Raw data set for the analysis shown above. The large gaps are often found in ground …
10Phase margin — In electronic amplifiers, phase margin is the difference, measured in degrees, between the phase of the amplifier s output signal and 360°. In feedback amplifiers, the phase margin is measured at the frequency at which the open loop voltage gain… …
