Hi All!
I has probe (B-field induction probe) with non linear amplitude-frequency characteristic. I has calibration table with 3 columns: frequency, amplitude, phase. I has output signal U(t) recorded with sample frequency Fs during rather long time.
Can I restore input signal (i.e. B-field amplitude B(t))?
I try to use (in Matlab) the next algorithm: FFT conversion -> apply calibration -> reverse FFT conversion.
But I obtain jump at splicing.
It seems I must create filter from my calibration table and filtered my signal. But how?
