Class of Optimal Polynomial Window Functions for Spectral Analysis of SignalsSIDELOBESThe problem of synthesis of low-order polynomial window functions with an arbitrarily specified decay rate of spectral lobes (optimal with respect to minimization of the maximum side lobe on a specified segment of ...
The Spectral Analysis of Random Signals Summary.When one calculates the DFT of a sequence of measurements of a random signal,onefinds that the values of the elements of the DFT do not tend to“settle down”no matter how long a sequence one measures.In this chapter, we present a brief ...

That is, we will assume that, by observing the signal at time t1, we apprehend the expected value of the ensemble of signals (Es(t1)), and not only the value of one particular realization; by also observing the signal at time t2, we now not only apprehend the value of Es(t2), ...
We developed scPrisma, a spectral analysis framework that uses topological priors over underlying signals in single-cell data, to allow for their inference, enhancement and filtering. The core of scPrisma uses spectral template matching between the spectrum (the eigendecomposition of the covariance mat...
The variation of signals is 0.43%. When the BSA solution is injected at t = 20 min, the BSA adhesion on the gold surface begins. Figure 4b shows the maximum change of kinetic SPR images for 25–35 min after the timer begins. It is the time interval when the BSA solution was ...
AS7341 is an 11-channel multi-spectral sensor for color detection and spectral analysis applications. The spectral response is defined in the wavelengths from approximately 350nm to 1000nm. 6 channels can be processed in parallel by independent ADCs while the other channels are accessible via a mu...
For example, in IEEE 802.22, the number of signals that must be sensed is quite small, including voice FM, analog and digital broadcast TV, and the 802.22 signals themselves. In such cases, spectral correlation may or may not provide the best engineering solution, but is almost always ...
