Variable: FFTNoV

Variable: FFTNoV

Specifies whether DIAdem uses NoValues for a data channel.

DIAdem cannot calculate an FFT if a time window of an amplitude channel contains NoValues. If you assign the value 1 to the variable FFTNov, DIAdem searches for an interval of the specified length that does not contain NoValues. Then DIAdem calculates the FFT for the found time window. If you specify more than one amplitude channel, or the interval length is to be specified automatically, or the time channel has NoValues, DIAdem does not search for the interval.
