18/08/1994  An efficient equivalent linear system with random coefficients is then proposed from which the power spectral density (PSD) is deduced. The use of corrective terms yields to an approximation of the PSD in the region of the third harmonic resonant frequency (as well as at higher harmonics). The analytical results are in excellent agreement with numerical simulations.

A spectral representation of the mixing process shown in Figure 1 appears in Figure 2. The 70MHz IF signal is translated to the 1500MHz RF frequency via a single-stage mix. The low-side spectrum at 1360MHz is inverted, while the high-side spectrum is not. Figure 2. Shown is a spectral representation of a 70MHz IF bandpass signal and the result of mixing it with a 1430MHz sinusoid. The high ...

Cross-correlation and cross-spectral density functions can be used to describe the autocorrelation and spectral density functions of the output of LTI systems (e.g., filters). The cross-correlation function is also useful in time-delay estimation while the cross-spectral density is used in adaptive beamforming where a matrix form of cross- and auto-spectral densities characterize measurements ...
