- The most commonly used windows include the Rectangular, Triangular, Hanning, Hamming, and Blackman types.
- Important differentiating aspects of these windows are the main lobe width and sidelobe magnitudes of their spectra.
- The Rectangular window and its associated spectrum (interpolated) are shown in Fig. 5.
- The Triangular window and its associated spectrum (interpolated) are shown in Fig. 6.
- The Triangle window can be computed as:

(12) - The Hanning window and its associated spectrum (interpolated) are shown in Fig. 7.
- The Hanning window can be computed as:

(13) - The Hamming window and its associated spectrum (interpolated) are shown in Fig. 8.
- The Hamming window can be computed as:

(14) - The Blackman window and its associated spectrum (interpolated) are shown in Fig. 9.
- The Blackman window can be computed as:
