Abstract

188,483. Walker, H. C. Oct. 4, 1921. Thermionic modulating systems.-A modulating valve F is connected in the grid circuit of a power or generating valve H in parallel with the usual grid leak resistance D, the grid circuit of the modulating valve F being subjected to the signal potential variations, such as those arising from a microphone circuit K, J. The aerial inductance B is connected in the plate circuit of the power valve H and is coupled to the grid inductance coil C. Other modulating valves in series or in parallel with the valve F may be used.
