Fig. 7(a) — p^/po versus ?/, (a) using QC as the parameter, for A; = 2.5, C = 0.1, 

 and 6 for maximum small-signal gain (Cases 2, 10, and 19) ; (b) using h as the param- 

 eter, for k = 2.50, C = 0.1 and QC = 0.2 (Cases 10, 11, 12 and 13); and (c) using 

 C as the parameter, for k = 2.50, QC = 0.2 and h for maximum small-signal gain 

 (Cases 9, 10 and 14).
