Multiplier Improves the Dynamic Range of Echo Systems (HA-2556, HA-5177) Application Note November 1996 AN9515.1 Introduction In an echo system the returned signal amplitude is a function www.datasheet4u.com of the distance to the target, and it can be expressed mathe- matically as function of time. An echo system with a ﬁxed gain preamp has poor dynamic range because close targets (short return times) have high signal amplitudes while distant targets (long return times) have much lower signal.
