MATLAB had a function called 'pyulear' that's used to model a signal's PSD. It made me wonder wheteher or not I can reconstruct a signal based of its PSD. I know that PSD can be created using FFT and I am trying to find the fft of a signal from its PSD. I had tried the cod...
Signal detection means performs the spectrum sensing as a function of the cyclic spectrum and power spectral density (PSD).ガオ,ウェンチェン,ホウ‐シン

due to the lack of moving parts. An electronic circuit monitors the flow rate internally and advises if the flow rate in the input line falls below a predefined minimum threshold. The device offers a flexible programmable massaging of the low-flow signal to the central controller. The Dräger...
The characteristic of PSD with two dimensional tetra-lateral is analyzed.A design method of signal processing circuit based on single-chip microcomputer for two dimensional PSD is introduced.This method includes hardware design,nonlinear correction by software,elimination of background light and dark curr...
I want to represent 3 signals on a waterfall plot to see how the signal changes over time fs = 1000; % Sampling frequency t = (0:fs)/fs; % One second worth of samples A = [1 2]; % Sinusoid amplitudes (row vector) A1 = [3 4]; ...
When you decompose a signal using PSD, you're breakingit down into its component frequencies. Each of these frequencies manifests as a spectral line on the PSD plot. Determining the optimal number of spectral lines for your analysis can be tricky. Too few lines might not capture all the ...
