Hi All,
This is regarding the FFT and IFFT.
Actually,If doing FFT and the come back to inverse FFT,not getting the same waveform in timedomain after IFFT, it is changed on x axis and y axis both.
During analysis,It is found that FFT works fine and generates a complex buffer of N/2 samples BUT as i want to plot this waveform also so have to convert the complex data buffer in to real data buffer as double type for ploting the waveform with magnitude(y-axis).As for ploting the waveform,double array data is going to storing globally so output complex data buffer during FFT is disappeared after calculating the magnitude.
Now for calculating the Inverse FFT, Want the input data as complex data array so CAN YOU LET ME KNOW HOW I CAN GET COMPLEX DATA (OUTPUT OF FFT) FOR INVERSE FFT (AS INPUT DATA).
Please reply me ASAP.
Thanks & Regards,
