| Abstract: | This paper describes design principles and methods of the preamplifiers of acoustic emission instrumentations. This kind of preamplifier is a low-noise, high sensitivity and wide band amplifier. The paper also points out the selection methods of circuit parameters and the test of the characteristic indexes of the preamplifier. |
