11. Distorted wave forms may not decode properly or may include harmonics that cause falsing. 12. Synchronous wave forms occur at regular periodic intervals, whereas asynchronous wave forms are irregular. 13. The wave form is coded and signal processing is improved. 14. We went through thousands of wave forms for the case. 15. Problem is, the wave forms never match each other exactly. 16. Synchronous wave forms occur at regular periodic intervals, whereas asynchronous wave forms are irregular. 17. When a shock wave forms , the local air pressure increases and then spreads out sideways. 18. The computer analyzes the wave form and sends an alert wirelessly to a central location. 19. Modeling this type of instrument is child's play using the FS1R using the formant wave form . 20. One such change is that shock waves form .
