signal with the sampling rate of 50 Hz. The signal is a 1*1576800000 vector, It looks impossible to use spectrogram function to plot spectrogram because normal computer does not have enough storage to calculate

I want to create a power spectrum vs frequency plot of an audio signal I have. I tried using the following code: [speech, f1] = audioread('outputTSNRcut.wav'); [noise, f2] = audioread('input2noise.wav'); [speechInput,fspeech] = pspectrum(speech, f1); [noiseInput, fnoise] = p...
For time-domain data, theFrequency functionplot shows the empirical transfer function estimate (etfe). For frequency-domain data, the plot shows the ratio of output to input data. The frequency-response plot shows the amplitude and phase plots of the corresponding frequency response. For more info...
Open in MATLAB Online I am having difficulty in finding a high-resolution frequency spectrum even though I have a pretty large number of time domain data samples (1999999 data points). The fundamental frequency peak in FFT is with a resolution of 50 Hz when I use fft(). I h...
How to extract the frequency and amplitude from a FFT and save the values in separated tables?You can use the function findpeaks of the Signal Processing Toolbox™ to find the two peaks and their frequency, if you have that toolbox read the documentation a...
I changed your code to plot the full amplitude spectrum. This fixes the warning error, and the frequency plot extends up to 100 kHz. More later. 1 Comment William Rose on 12 Aug 2024 Edited: William Rose on 12 Aug 2024 Open in MATLAB Online Ran in: @ANAS HAMZAH, ...
This is completed for the functions of this situation, however for many programs, the whole spectrum is thrilling. In the subsequent line, the facts with the intention to be used for the abscissa is ready with the aid of using the sampling frequency and the quantity of samples in the time...
I connect it to the matlab, but when I want to transmit the measurement result ,I can't find any methods to implement it. The measurement result is the power value, frequency and time. So I would like to know how to implement the data transmission from...
That's a powerful and useful theorm, but it can produce a spectrum that is surprising and confusing to the new student. For now, you can keep things simple by sampling at greater than twice the signal's highest frequency (instead of twice its bandwidth). In that case, y...
