fi*=0) the R.M.S. of the input voltage will have a Afinite value —^, but the detecting current will be zero (equation v2 23). In order to insure that measurement of the detection co-efficient shall have any meaning the extent to which the waveimpressed on the input of the detector is modulated must… … Fig. 204. the relation between plate current and grid potential, it is evidentfrom the explanations given in Section 53 that the intercept OA which represents the negative grid potential necessaiy to reduce -pithe plate current to zero is —. If we now apply a constant jp grid potential Eg= ^ and…
