Abstract
The theory of frames is fundamental to time-frequency (TF) or time-scale signal expansions like Gabor expansions and wavelet transforms. We propose a TF analysis of frames via two “TF frame representations” called the Weyl symbol and Wigner distribution of a frame. The TF analysis shows how a frame´s properties depend on the signal´s TF location and on certain frame parameters
