-.+===== What is meant by time-frequency trade off? ===== 
 + 
 +With the mtmconvol method of **[[:​reference:​ft_freqanalysis]]** we compute time-resolved estimates of spectral power. As in most of the methods that achieve a time-frequency decomposition (irrespective of whether it used sliding window Fourier transforms, wavelet convolution,​ or Hilbert transforms) one important thing to keep in mind is that each point estimate of signal power (at a specific frequency and time point) is the result of integrating the signal over a certain time-frequency tile. In other words, each of the point estimates reflect the properties of the signal in a more or less well-defined time window, as well as in a more or less well-defined spectral band.
