Acoustic white noise generator |
摘要 |
A narrow banded acoustic transducer is driven by a VCFO whose output is varied by input signals of variable amplitude. One can simulate acoustic emissions for purposes of calibrating transducers which monitor a structural part for such emissions. Different signals for the control of the VCFO are generated to provide for specific test pulses.
