Abstract :
Bounds on the output of a linear system are developed and used to reexamine the nature of the truncation error eNin the sampling expansion of a band-limited signal . It is shown that if has finite energy, then the maximum of is bounded by the mean-square value of the error in the approximation of by a truncated Fourier series. If has finite power, then the mean-square value of eNis bounded by the maximum of .
