B)IFT
C)IFFT
D)QPSK

Question

Quizplus · Accepted Answer

FFT stands for Fast Fourier Transform which is a specific algorithm to compute DFT (Discrete Fourier Transform). Therefore, option A is the correct choice. Option B represents Inverse Fourier Transform (IFT) which is the reverse process of DFT. Option C (IFFT) is a specific algorithm to compute the inverse DFT. Option D represents Quadrature Phase Shift Keying which is a modulation technique used in digital communication systems and has no relation to FFT.
