From e1071 v1.7-3
by David Meyer

##### Computes the Coefficients of a Hamming Window.

The filter coefficients \(w_i\) of a Hamming
window of length
`n`

are computed according to the formula
$$w_i = 0.54 - 0.46 \cos\frac{2\pi i}{n-1}$$

- Keywords
- ts

##### Usage

`hamming.window(n)`

##### Arguments

- n
The length of the window.

##### Value

A vector containing the filter coefficients.

##### References

For a definition of the Hamming window, see for example Alan V. Oppenheim and Roland W. Schafer: "Discrete-Time Signal Processing", Prentice-Hall, 1989.

hamming.window(10)
x<-rnorm(500)
y<-stft(x, wtype="hamming.window")
plot(y)
# }
