Web1 Answer. The simplest correct answer is that DFT is in O ( N e 3). This comes from the idea that you are ultimately diagonalizing a Hamiltonian with dimension proportional to the number of elections and diagonalization is technically O ( n 3). In reality, DFT is a bunch of steps and different steps are rate-limiting in different context. If we ... WebThe DFT is in general defined for complex inputs and outputs, and a single-frequency component at linear frequency $f$ is represented by a complex exponential $a_m = \exp\{2\pi i\,f m\Delta t\}$, where $\Delta t$ is the sampling interval..
