    An economy in the frequency-channel width occupied by stations sending telephony signals can be made by removing one sideband from the transmitted spectrum. This operation however produces a distortion of the received signals which can only be minimized by an intensification of the carrier component compared with the side-band component. If this intensification is performed at the transmitter the ... View full abstract»

    A formula adapting Maxwell's solution for a plane grating to the plane triode differs from those obtained by previous workers. The triode is simulated by a diode whose electrode separation exceeds the cathode-grid clearance by an amount which is calculated from electrostatic considerations. Corresponding results are derived for the cylindrical triode by means of conformal representation, and are s... View full abstract»

    Data on the ordinary-wave critical frequencies and virtual heights of the ionospheric layers are presented for the period indicated in the title. The monthly average values of the maximum usable frequencies for undisturbed days, for radio transmission by way of the regular layers is also provided. View full abstract»
