A LINEAR-TIME ALGORITHM FOR EVALUATING SERIES OF SCHUR FUNCTIONS CY CHAN, VESSELIN DRENSKY, ALAN EDELMAN, AND PLAMEN KOEV Abstract. We present a new algorithm for computing all Schur functions sλ(x1, x2, . . . , xn) for all partitions λ of integers not exceeding N in time O(n2K ), where K ≡ #{λ| |λ| ≤ N} N N is the number of

INTRODUCTION: The experiment uses the L.J.Electronics Modicom-1 board to investigate the sampling of signals, and the filter effects on the reconstruction of the original signal from the sampled input. The sample/Hold operation is also investigated in this experiment. The Modicum -1 board allows an analogue signal to be sampled at a number of different rate(2kHz,4kHZ,8kHZ,16kHz,32kHz).The pulse width is varied in the steps of 0% from 0 to 90
