Bilinear time}frequency distributions have been widely utilized in the analysis of nonstationary biomedical signals. A problem often arises where the time}frequency components with small-amplitude values cannot be displayed clearly. This problem results from a masking e!ect on these components cause
AI~STRACT : A generalized category of cone-shaped kernels is proposed. Analysis of the kernel in the 2-D time, 2-D frequency, and ambiguity domains is pet;formed. The shape of this kernel in the 2-D time plane is bow-tie, which effectively suppresses cross-terms especially in the frequency direction
