DADiSP / CFC 1.5

Channel Frequency Class Module

DADiSP/CFC implements SAE J211 and ISO 6487 phaseless 4 pole Channel Frequency Class (CFC) digital filters widely used in impact and crash test analysis.

The CFC Module supports all four channel frequency classes, CFC 60, CFC 180, CFC 600 and CFC 1000. User defined CFC frequencies outside these classes are also supported.

Input data is processed by the CFC filter in one step, where the filter is designed as per the selected specification and the data is filtered in the time domain with a high precision phaseless Butterworth digital filter.
