Summary
| Description |
English: This is a portion of the normalized *DTFT* for a rectangular windowed sinusoid. The actual frequency of the sinusoid is indicated as "0" on the horizontal axis. The unit of frequency is "DFT bins"; that is, the *integer* values on the frequency axis correspond to the frequencies sampled by the *DFT*. The plot depicts the case where the window cuts out an integer number of periods. The maximum value of the spectrum is accurately measured (index 0), all the other bins of the DFT are exactly zero. |
