The graphs A, B, and C in figure 9 indicate in a general 

 way the trend of the gain error E when the parameter N. 

 increases with h and r c fixed. Although the gain error E 

 in the frequency-response curve decreases as N increases 

 for a fixed h and r c (us can be seen from the graph in 

 figure 9)>a large N requires more samples of the original 

 time function and necessitates more computer tiiae for the 

 smoothing operation.

Figure 9- Variation of the maximum absolute gain error E 

 with N for parameters h and r c held constant. Observe 

 that increasing N beyond 60 or 80 does not significantly 

 decrease the gain error E.
