Blackman Window. The Blackman window suppresses the side lobe magnitudes
in the frequency region lower than the hamming window does and suppresses
leakage even farther. However, it has inferior frequency resolution.

Triangle Wave Window. The triangle wave window is a convolution of two square
windows half the width of the window. Therefore, the triangle wave window
frequency spectrum is the product of the square wave windows.
