in Fig. 10 and shown in the form of an oscilloscope pattern in Fig. 

 16(d). Conditions pertaining at the crossover point were described by 

 equation (3.13), which stated: 



or, since pQ = Qs 



v\Qkf = 1 + v\2Q^)\ 



(Qskf = 1 + (2^35)^ 



Hence the two frequencies corresponding to the crossover point are 

 given by 



and their difference, A5, by 



Equation (4.7)*' ^ provides an experimental method of determining k 

 since A8 can be accurately measured and Qg is known from previous tests.
