The thermionic triode as rectifier

The performances of the triode rectifier arrangements used in wireless telegraphy, with signals of various strengths, and with or without a superposed local heterodyne oscillation, are investigated theoretically and experimentally. The theoretical results throughout are illustrated numerically by reference to a certain well-known pattern of triode, and in the more fundamental cases the theoretical deductions are compared with precise experimental measurements made at low frequency. The agreement is found to be very close. Experimental curves for this pattern of triode are given also in cases where it has not seemed practicable to evolve theoretical formulÿ.
