The traditional approach to the three-phase space vector theory and its extension to polyphase systems (5, 7, 9 phases and more) does not give a complete insight. Due to the assumption that ...
An experimental installation of polyphase broadcasting is described using 1000 watts carrier power on a frequency of 1000 kilocycles. Fidelity measurements made of the modulated field intens...
