What is the output of IFFT operations, continuous or discrete time? Assume we have a sequence of symbols 
$$S= \{0, 0, 1+j, -1-j, 0 ,0 , 1+j,-1+j\}$$

and that this sequence is a frequency domain sequence and will be input to an IFFT operation.

Is the output a continous time or discrete time signal?

Thanks
The FFT is just a fast algorithm for evaluating the discrete Fourier transform (DFT). The domains for the DFT are discrete in both time and frequency. So, the result of an inverse DFT using the inputs you showed above will be a discrete-time signal.
