## PC-SIGNAL: PC-Based Dynamic Signal Analysis Software 

- PC-SIGNALTM is a post-process dynamic signal analysis software for rotating machinery. The package offers dramatic time savings by eliminating the programming effort formerly needed  to perform sophisticated signal analysis.  PC-SIGNAL simplifies every aspect of the signal processing operation by effective application of its graphical user interface.  It expedites all steps:  from importing raw signal data files, through choice of processing algorithm,  to outputting the results.

**      ****GOVERNMENT/SCIENCE APPLICATIONS**
**Actual:  The unique signal analysis software of PC-SIGNAL has aided NASA engineers in performing diagnostic evaluation for bearing defect signature, cavitation-induced vibration signature, and anomaly identification in analyzing dynamic signals of propulsion systems  (Fastrac, X-33, SSME) along with engine component-level unsteady data.**
**Potential:   PC-SIGNAL has applications for general dynamic data analysis and health monitoring/diagnostics of transmission systems in rocket engine, aircraft, helicopter, and production-line machinery.**
**Other USG application: PC-SIGNAL has been utilized by Army RTTC for  post-test vibration data analysis. The easy-to-use software  design of PC-SIGNAL has significantly reduced analysis time for quick evaluation of large volumes of test data and has enhanced  the productivity of RTTC’s  data analysis.  The PC-based software provides a cost-effective solution when compared to its expensive analysis predecessor****. ****	****	**
