.. Hi .. I know it sounds just too simple, but imagine I have just frequency data and I need the time data out of it to plot some other magnitude data over the time in 1/samplerate.
Am I just going to say
time = ifft(freq)
?
Or should I be cautious because the freq vector might be complex?
TY

ifft function transforms the complex signal data from frequency domain to time domain where the time difference between the successive samples of the time domain data equal to the inverse of Sampling Frequency.
