摘要:
A circuit for measuring the energy in randomly occurring bursts of rf energy is described. The circuit is linear to within 10% (over a 15 dB dynamic range) for frequencies up to 1.5 MHz. Examples are given of its use with acoustic emission data from a martensitic phase transition in the indium thallium system and from a nondestructive test on a filament wound vessel.
