The list of aircraft carriers by configuration contains active aircraft carriers organized by the specific configuration of aircraft carrier designs. This list excludes seaplane carriers or helicopter carriers .
In communication theory, time-varying phasors are used for analyzing narrow-band signals, whose signal bandwidths in the frequency domain are considerably smaller than the carrier frequency. [1] [2] Time-varying phasors are mostly used for analysis of frequency domain of band-pass systems. [2] [1] The method uses classical impulse response. [1]
A constellation diagram is a representation of a signal modulated by a digital modulation scheme such as quadrature amplitude modulation or phase-shift keying. [1] It displays the signal as a two-dimensional xy -plane scatter diagram in the complex plane at symbol sampling instants.
The carrier-envelope phase (CEP) or carrier-envelope offset (CEO) phase is an important feature of an ultrashort laser pulse and gains significance with decreasing pulse duration, in a regime where the pulse consists of a few wavelengths. Physical effects depending on the carrier-envelope phase fall into the category of highly nonlinear optics.
In Fluorescence lifetime and spectral imaging, phasor can be used to visualize the spectra and decay curves. [1] [2] In this method the Fourier transformation of the spectrum or decay curve is calculated and the resulted complex number is plotted on a 2D plot where the X-axis represents the real component and the Y-axis represents the imaginary ...
LO is the local oscillator - the carrier sine wave being modulated I(t) and Q(t) are the time-series data for the in-phase and quadrature components. S is the signal . IQ data has extensive use in many signal processing contexts, including for radio modulation, software-defined radio, audio signal processing and electrical engineering.
Phasor notation (also known as angle notation) is a mathematical notation used in electronics engineering and electrical engineering.A vector whose polar coordinates are magnitude and angle is written . [13] can represent either the vector (, ) or the complex number + =, according to Euler's formula with =, both of which have magnitudes of 1.
The Casablanca-class escort carrier was a series of escort carriers constructed for the United States Navy during World War II. They are the most numerous class of aircraft carriers ever built. Fifty were laid down, launched and commissioned within the space of less than two years – 3 November 1942 through to 8 July 1944.
