Abstract
Motivated by the well‐established phase derivative embedded technique, this study devotes to sharper uncertainty principles related to the Lp‐norm type of uncertainty product, giving rise to two kinds of uncertainty inequalities that improve the classical result through providing tighter lower bounds. The conditions that truly reach these better estimates are obtained. Examples and simulations are carried out to verify the correctness of the derived results, and finally, possible applications in time‐frequency analysis are also given.
