Importance of scalogram
Witryna7 maj 2008 · The analysis of the scalogram as the instantaneous frequency estimator is performed for any FM signal regardless of the mother wavelet. Accurate expressions for the bias and the variance of the estimator are derived, and reveal that the bias and the variance are signal dependent. http://web.mit.edu/~gari/teaching/6.555/lectures/ch15_bss.pdf
