Abstract:
The program involves a study aimed at advancement of the state of the art of electrical measurements. Efforts during this period have been devoted to a study of the use of voltage-variable capacitors in a single-sideband generator and in a low-pass-filter parametric amplifier; to a consideration of the application of an improved Hall device in a single-sideband generator, a balanced modulator, a phase modulator, a cascade phase modulator, a direct frequency modulator, and an audio-frequency wattmeter; to an investigation of the employment of the magnetoresistive effect in a multi-element stripline attenuator; and to a study of field effect, depletion effect, ferroelectric effect and piezoelectric effect for possible use as electric field sensors.
