Being a non signal processing science student I have limited understanding of the concepts. I have a continuous periodic bearing faulty signal (with time amplitudes) which are sampled at $12\textrm{ ... 15 votes 3 answers 6k views ### When can we write Heisenberg uncertainty Principle as a equality? We know that Heisenberg uncertainty Principle states that $$\Delta f \Delta t \geq \frac{1}{4 \pi}.$$ But (in many case for Morlet wavelet) I have seen that they changed the inequality to an equality.... 9 votes 1 answer 396 views ### How can I estimate the spatial resolution of consumer grade electronics? I have been looking at stereo vision applications, and one working example involves using two USB web cams, mounted together and calibrated. Is there a way to estimate the theoretical spatial ... 2 votes 2 answers 2k views ### Morlet wavelet time and frequency resolution I want to calculate Morlet time and frequency resolution. the Morlet wavelet function is define as :$\psi(t)=\frac{1}{\sqrt{\pi f_b}}e^{j2\pi f_c}e^{-t^2/f_b}$Note: I know the answers, but I don't ... 20 votes 2 answers 8k views ### Does using the Goertzel algorithm actually give better frequency resolution? I am reading this article, and I am getting a little confused by the author's liberal use of 'frequency resolution' regarding the Goertzel Algorithm. Basic question: Does using the Goertzel algorithm ... 9 votes 1 answer 3k views ### What is the maximal frequency resolution for Matlab's STFT implementation spectrogram()? Matlab's spectrogram() function calculates the STFT of a signal. It describes its NFFT argument as follows: ... 4 votes 1 answer 3k views ### Uncertainty principle - Duration bandwidth principle In one of NPTEL courses about time-frequency analysis, the professor said that the duration bandwidth principle is$\sigma_t^2 \sigma_\omega^2 \ge \frac{1}{4}$. He added that the formula making use ... 2 votes 1 answer 3k views ### use chirp z transform for spectral resolution let us suppose that we some signal$x(t)\$,which consist of sinusoidal components and white noise,i would like to know how to use chirp z transform for improving spectral resolution?i found this ...
