Hanning Window Solution

Follow our step by step solution on how to calculate Hanning Window?

FIRST Step Consider the formula

W hn = \frac{1}{2} - (\frac{1}{2}) \cdot \cos (\frac{2 \cdot π \cdot n}{W ss - 1})

Next Step Substitute values of Variables

∴

W hn = \frac{1}{2} - (\frac{1}{2}) \cdot \cos (\frac{2 \cdot π \cdot 2.11}{7 - 1})

Next Step Substitute values of Constants

∴

W hn = \frac{1}{2} - (\frac{1}{2}) \cdot \cos (\frac{2 \cdot 3.1416 \cdot 2.11}{7 - 1})

Next Step Prepare to Evaluate

∴

W hn = \frac{1}{2} - (\frac{1}{2}) \cdot \cos (\frac{2 \cdot 3.1416 \cdot 2.11}{7 - 1})

Next Step Evaluate

∴

W hn = 0.798112437482808

LAST Step Rounding Answer

∴

W hn = 0.7981
