...The second complication could come from a highly complicated phase function, as discussed in Huang et al. (1998); then the phase plan will not be a perfect circle. Any deviation from the circle will result in the amplitude being different from unity. Huang and Long (2003) and Huang et al. (2005) conducted detailed comparisons and found the result quite satisfactory....

...In order to obtain meaningful instantaneous frequency, restrictive conditions have to be imposed on the data as discussed by Gabor (1946), Bedrosian (1963) and, more recently, Boashash (1992): for any function to have a meaningful instantaneous frequency, the real part of its Fourier transform has…...

...Therefore, the parameter, ν, defined as N21 −N20 = 1 π2 m4m0 −m22 m2m0 = 1 π2 ν2, (3.7) offers a standard bandwidth measure (see, for example, Rice 1944a, b, 1945a, b; Longuet-Higgins 1957)....
