will be shown later, the ratio ~ can deviate considerably from unity before resulting in any serious duninution of the effectproduced upon the organs of hearing. If we put ZQ=nrp equation (33) becomes: (jr Tg cos (j> (36) which clearly shows the importance of the mutual conductance - or the… … i^.C. Input Fig. 93. 64. Experimental Verification of Amplification Squations. The amplification was determined experimentally as a functionof the tube parameters with the circuit arrangement shown inFig. 93.^ This circuit was made non-inductive throughout.The input voltage could be varied by means…
