摘要：
We report a method for constructing bandpass functions that approximate a given analytic function with arbitrary accuracy over a finite interval. A corollary is that bandpass functions can be obtained which oscillate arbitrarily slower than their minimum frequency component, a counter-intuitive phenomenon known as suboscillations.
