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. U
se 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.

t details of how to compute its values were published in the article; Impulse-Response Testing Lets a
Single Test Do the Work of Thousands, by John Pickerd, EDN magazine, April 27, 1995.
