IN this method the frequency of a radio-frequency oscillator is modulated by a sinusoidal audio-frequency voltage, and the resultant radio-frequency voltage is applied to a transmitting quartz ...
THE increasing use of ultra-short wave radio communication has created a need for the measurement of oscillating electric currents, potential differences, and field strengths, at very high frequencies ...
