Popis:	This tutorial paper defines the various concepts of bandwidth used in RF-interference measurements, explains their significance, and indicates their inter-relationships. The approach is to examine the conventional selectivity curve of an IF amplifier in terms of bandwidths to steady-state signals. Impulse response of the IF amplifier is also presented and the importance thereto of the coefficient of coupling in double-tuned IF transformers is discussed. For both steady-state and transient signals, the basic concepts of effective bandwidth are presented. This concept is applied to IF amplifiers for three different types of effective bandwidth, steady-state, random noise, and impulse, and the significance of each is examined. For any given IF amplifier, each is related to the response of a given physical system and, hence, they are interrelated. These inter-relationships are indicated.
