Members
| Member name | Value | Description |
|---|---|---|
| None | 0 | Analyzes transients for which duration is shorter than the window length. You can also use this window type to separate two tones with frequencies close to each other but with almost equal amplitudes. |
| FlatTop | 1 | Measures single-tone amplitudes accurately. |
| Hanning | 2 | Analyzes transients for which duration is longer than the window length. You can also use this window type to provide better frequency resolution for noise measurements. |
| Hamming | 3 | Analyzes closely-spaced sine waves. |
| Gaussian | 4 | Provides a good balance of spectral leakage, frequency resolution, and amplitude attenuation. Hence, this windowing is useful for time-frequency analysis. |
| Blackman | 5 | Analyzes single tone because it has a low maximum side lobe level and a high side lobe roll-off rate. |
| BlackmanHarris | 6 | Useful as a good general purpose window, having side lobe rejection >90dB and having a moderately wide main lobe. |
| KaiserBessel | 7 | Separates two tones with frequencies close to each other but with widely-differing amplitudes. |
