The thermionic vacuum tube and its applications (1920)
Van der Bijl, Hendrik Johannes, 1887- · New York McGraw-Hill Book, Co · leaf 187
e of the input voltage is nevergreater than E^; for distortionless ampHfication e must always 104 THERMIONIC VACUUM TUBE be less than Ey (see Section 60). Referring, for example, to Fig,81, it will be seen that E^ is the intercept cd when Eg^O orfd when Eg^cf. Taking the latter case it will be seen… … Oriel VoltageFig. si. thus introducing harmonics. Furthermore, since the maximumvalue of sin pt is unity and its odd powers vanish on integrationthe expression in the parentheses can be expanded into a series,the integral of which converges sufficiently rapidlj to enable us tocompute the…
