A Spectral Method for Testing Radio Receiver's Immunity to Interference

The present paper discusses the problem of the assessment of radio receiver immunity to the interference due to emissions occurring outside the bandwidth employed for the reception of a wanted signal. It is found that with the emergence of new technologies in the domain of radio receiver design and as a result of the increasing application of the electromagnetic spectrum, the problem in question has now become particularly conspicuous. The paper describes a method proposed for testing such an immunity with the aid of an impulse signal of a continuous frequency spectrum shaped by means of appropriate filters. Measurements are illustrated by examples.
