Abstract
Apparatus for detecting the evolution of an acoustic signal, comprising an acoustic sensor, as well as circuits for the amplification, filtering, detection and measurement of the effective value of the signal supplied by the sensor. The apparatus comprises a smoothing circuit, a sawtooth generator, an adder, a circuit for adjusting the effective value by straight segments and a circuit for carrying out sequence tests. The apparatus is adapted for use in the monitoring of steam generators in fast neutron reactors.
