Sine Wave

Any curve plotted along an axis where the y-value moves above and below zero at a rate of y = sin(x). The Composite Index of Lagging Indicators is thought to be roughly a sine wave because interest rates and inflation, which make up the index, move in relation to each other in a way resembling the sine.

The basic discrete-level pseudo-chirp is the binary one (called also signum-chirp or Non-Return-to-Zero (NRZ) chirp), waveform of which represents the signum-function of the respective sine-wave chirp as A-sgn([V.sub.ch](t)), thus having values of { [+ or -] A} only - see Fig.
Most sine-wave models, such as the Xantrex SW Series and most OutBack inverters, include multiple AC inputs for grid and generator power, and computer interface options which will allow you to program and monitor the inverter from your computer.
As discussed by Garcia-Perez and Peli, departures from DeVries-Rose behavior (i.e., a slope of 0.5 in log-log coordinates) are clearly apparent in many empirical data bearing on this issue, leading us to question the validity of the DeVries-Rose law for sine-wave gratings.
Second, we found that the modified sine-wave inverter produced a power noticeably inferior to the pure sine-wave power we'd gotten used to from the grid.
"We've designed what we call a sine-wave spar that is lightweight and structurally robust," said Geary Long, the F-22 internal-spar integrated-product-team leader for Boeing, "but we needed a process that would yield higher-quality parts again and again, throughout the life of the program.
The 63200A series provides 6 kW In a 4U-hlgh chassis, built-in digital microprocessors, master/slave parallel control, sine-wave dynamic loading, and a measurement accuracy of 0.015% + 0.015% FS, 0.04% + 0.04% FS, and 0.1% + 0.1% FS accuracy for voltage, current, and power measurement, respectively.
Absopulse Electronics' FTT 3K Series modular AC/AC frequency converter system uses microprocessor controlled, high frequency PWM technology to deliver 3-Phase, 3000VA continuous sine-wave output power, from a 3-phase input.
The sine-wave frequency range is 0.01 [micro]Hz to 30 MHz.
Thus, if the input voltage has a sine-wave shape, the input current also should have a sine-wave shape.
In the NI demo, a Compact RIO system induces a 200-kHz sine wave on the saw blade through a known impedance and monitors the sine-wave amplitude at the blade.
