测不准原理可以很容易地推广到“集中集合”不是区间的情况。这种推广适用于连续和离散时间函数，以及几种“集中”的度量(例如，和度量)。这些推广解释了信号恢复问题中有趣的现象，其中存在丢失数据、稀疏性和带宽限制的相互作用。
The uncertainty principle can easily be generalized to cases where the “sets of concentration” are not intervals. Such generalizations are presented for continuous and discrete-time functions, and for several measures of “concentration” (e.g.,andmeasures). The generalizations explain interesting phenomena in signal recovery problems where there is an interplay of missing data, sparsity, and bandlimiting.
