摘要：

Wavelets are a relatively recent development in applied mathematics. Motivated by the recent paper [On accumulated spectrograms, Trans. Amer. Math. Soc. 368 (2016) 3629-3649] by Abreu, Grochenig and Romero, we will prove in the present paper related results in the context of wavelets and time-scale analysis.
