Automatic Systems in Radioengineering Devices

摘要

The book examines, on the basis of automatic control theory, the basic automatic systems employed in contemporary radio engineering devices: systems for determining the direction of arrival of radio waves, self-excited oscillator, frequency control systems, systems for determining the time positions of pulses, and gain-control systems. Also described are the most commonly used measuring elements in these systems: amplitude, phase, frequency and time discriminators. (Author)
