Frequency Derivative/Integral - ONOSOKKI DS-2000 series Operation Manual

8. Frequency Derivative/Integral

The first/second order derivative operation and single/double integral operation can be performed for
data of the frequency region. Frequency derivative/integral operations can be performed for data of the
frequency region, such as power spectrum, frequency response function, etc. after completion of FFT
operation.
