Plate 11(g) for k = 3, m = 2, clearly shows an "undershoot" 
for the initial response. The initial response is on the order of 80 percent 
of that of the test wave form of Plate 11(b). This can be called an 
"undershoot" of 20 percent and is to be compared with an "undershoot" of 
25 percent predicted by Plate 8. The oscillations again exist only during 
the 5.88 microsecond time interval out to t = 5RC. 
These oscillograms thus provide a very satisfactory confirmation 
of the transient response predicted by the calculated step-transient response 
curves of Plate 8. Similar confirmations were obtained for all other values 
of terminating capacity considered in Plates 7, 9, and 10. 
12. From these results, selection of the most suitable cable termina- 
ting network may be made to satisfy various experimental requirements. 
Reference to these results should facilitate the determination of the optimum 
values of terminating network constants to be employed whenever modifications 
oto the recording equipment are considered.
