Tek-Exponential window
In the time domain, it is not a symmetrical bell shape as is the case with the other windows. Instead, it is exponential with a peak at the
20% position of the time domain gate. The frequency domain shape is triangular
.
Note: Use this window for impulse-response testing where the 20% position is the zero phase reference point. More of the
acquired data record length is used to capture the impulse response.
Exact details of how to compute its values were published in the article;Impulse-Response T

Thousands, by John Pickerd, EDN magazine, April 27, 1995.
