    There are considered the mechanism of radiation and reception in radio communication. The design of the transmitting equipment is compared with the design of the usual alternators and power plants of electrical engineering. The main problems encountered are described, and an account is given of the solutions obtained. The development of the Radio Central Station for telegraphy and telephony is dis...

    A number of types of Moorhead tubes are described, together with the mode of testing them and the specifications to be met. The tubes obtained are classified as detectors or amplifiers, which types the authors regard as separate and generally non-inclusive. The effects of small variations of a number of the tube dimensions are exhaustively studied, and conclusions are drawn as to the effect of var... View full abstract»

    The general construction and details of the design of cathode ray tubes are given. The brightness of the spot obtained, the sensitivity of the tube, and its behavior in use are described. The various excitation sources available are compared. A number of applications of such tubes to radio research (for example, spark gap characteristics, and associate synchronizing of oscillating triodes) are des... View full abstract»

    The general theory of coupled radio frequency circuits is developed, for systems having two degrees of freedom, and for the resonance and non-resonance conditions. The theory is appilied to determine the frequencies and damping factors for inductively coupled, directly coupled, and electrostatically coupled circuits. View full abstract»
