Windowing functions.
| vec itpp::hamming | ( | int | size | ) |
Hamming window.
The n size Hamming window is a vector 
where the 
th component is
![\[ w_i = 0.54 - 0.46 \cos(2\pi i/(n-1)) \]](form_243.png)
Referenced by itpp::FIR_Fading_Generator::Jakes_filter().
| vec itpp::hanning | ( | int | n | ) |
Hanning window.
The n size Hanning window is a vector where the th component is
![\[ w_i = 0.5(1 - \cos(2\pi (i+1)/(n+1)) \]](form_244.png)
Observe that this function is not the same as the hann() function which is defined as in matlab.
| vec itpp::hann | ( | int | n | ) |
Hanning window compatible with matlab.
The n size Hanning window is a vector where the th component is
![\[ w_i = 0.5(1 - \cos(2\pi i/(n-1)) \]](form_245.png)
| vec itpp::blackman | ( | int | n | ) |
Blackman window.
The n size Blackman window is a vector where the th component is
![\[ w_i = 0.42 - 0.5\cos(2\pi i/(n-1)) + 0.08\cos(4\pi i/(n-1)) \]](form_246.png)
| vec itpp::triang | ( | int | n | ) |
Triangular window.
The n size triangle window is a vector where the th component is
![\[ w_i = w_{n-i-1} = \frac{2(i+1)}{n+1} \]](form_247.png)
for n odd and for n even
![\[ w_i = w_{n-i-1} = \frac{2i+1}{n} \]](form_248.png)
| vec itpp::sqrt_win | ( | int | n | ) |
Square root window.
The square-root of the Triangle window. sqrt_win(n) = sqrt(triang(n))
