Disadvantage of Hanning Window Over Rectangular Window:
Advantage of Rectangular Window:
- The rectangular window has a narrower main lobe compared to the Hanning window.
- This narrower main lobe allows for better frequency resolution and localization of spectral components.
Disadvantage of Hanning Window:
- The Hanning window has a wider main lobe compared to the rectangular window.
- This wider main lobe results in a decrease in frequency resolution and localization of spectral components.
- The wider main lobe also leads to more spectral leakage and increased side lobes in the frequency domain.
- The increased side lobes can introduce unwanted noise and distort the frequency spectrum of the signal being analyzed.
Therefore, the main disadvantage of the Hanning window over the rectangular window is the wider main lobe, which can affect the accuracy and precision of frequency analysis in signal processing applications.
