can be transformed into frequency domain and frequencies can extracted by plotting. And you need to have a prior knowledge of sampling frequency with which the signal was sampled in order to calculate the frequencies present. You can use"fft"to convert signal from time domain to frequency dom...

Calculating SNR, THD, SFDR, and SINAD from an FFT is relatively straightforward. I do not have Matlab code for this, but here is the process, assuming you start with a complex FFT generated by Matlab. Also, I am assuming that your input frequency is "Mutual...
The AP supports 2x2 MIMO on the 5 GHz frequency band, so the number of spatial streams is also 2. When an AP communicates with STAs, the actual link setup rate depends on the lower value. For example, if the AP supports 4x4 MIMO and a STA supports 2x2 MIMO, the AP sets up a ...
convolution in the frequency domain. Therefore, during ADC conversion, the spectrum of the ADC sampling clock is convolved with the pure sine wave input signal, and, thus, jitter on the sampling clock or phase noise will appear in the FFT spectrum of the ADC output...
If the noise is additive with the majority of the noise power outside of the frequency range of the signal, the signal can be estimated by filtering out most of the noise. The noise is then estimated by subtracting the signal estimate from the noisy me...

EEG coherence is a function of frequency; thus it is commonly presented in a spectral manner (coherence values in every frequency of the spectrum), in contrast, the correlation function has been employed mainly to search periodic components of bioelectrical signals, and normally appears as punctual...
The periodogram is proportional to the magnitude-squared DFT. The scaling factors that make it not equal to the magnitude-squared DFT are precisely the factors that come from the derivation of the periodogram from the biased autocorrelation sequence and therefore are exactly...
