Electron-tube voltmeter concepts in the mid-frequency range

FROM TIME to time the AIEE sponsors papers of a tutorial nature designed to expound some phase of electrical engineering for the benefit of the general reader rather than for the specialist. This paper is of the tutorial type, treating some of the problems in electron tube voltmeter design and operation, without trying to be all inclusive. The term mid-frequency range is used to indicate that none of the effects which set the upper and lower frequency limits of the instruments are considered.
