SPAR ACOUSTIC SIGNAL AMPLIFICATION SYSTEM,

Abstract

The report describes the design philosophy, circuit diagrams and test results of the acoustic signal amplification system for the SPAR vehicle. Any of 15 hydrophones may be connected to any of 6 amplification channels. Each channel has a special ground loop hum rejection system, a precision attenuator of up to 60 db, and a total of 40 db of well stabilized gain following the hydrophone. (Author)
