The method is based on using finite (truncated) Fourier series for representation of signals. Nonlinear transformations are implemented in two phases: harmonic linearization using only one sine wave in phase space, and general Chebyshev transformation of waveforms to return into true time domain ...

Mathematically representing the transmitted signal and noise, we can either use a time waveform representation or a vector representation. With respect to the latter, we exploit the fact that any sinusoidal signal can be uniquely represented using three variables: ω (frequency), A (amplitude), and...

Using these FQTs, we propose 16 Fourier quadrature analytic signal (FQAS) representations with following properties: (1) real part of eight FQAS representations is the original signal, and imaginary part of each representation is FCQT of real part; (2) imaginary part of eight FQAS ...

Each input wavelength has a unique fringe representation, which is the basis of the Fourier-transform relation between the input spectra and the output interferogram. Multiple input waveguides in the waveguide SHS is an important advantage over the existing single-mode-input AWG spectrometer, since ...
It's pretty clear that two's complement representation can be thought of as a coding scheme in which the signal is coded from all zeros to all ones, with the first, most-significant bit (MSB) acting as an inverted sign bit; 0 for positive values, 1 for negative values. With this sign...
