A Study of Delay Lines and the Development of Design Criteria for HF Communications Receiver Noise Blankers.

Abstract

Atmospheric and man-made disturbances which result in noise pulses of random amplitude and randomly spaced in time have long been experienced in the communications field. Design features of an RF blanker for this type of nois are investigated. The specifications of functional blocks are established. One of the functional blocks of an RF blanker is a linear delay line. The main features and design methods for passive delay lines are investigated. An active RC circuit to realize the delay function is proposed. This network and another are constructed and their characteristics obtained. (Author)
