Double Exponential Pulse
(D_EXP.WFM)
D 8
This is the rising and falling exponential function pulse. Made with the equation
editor.
Figure D 5: Double Exponential Pulse Formula and Waveform
Constants k1 and k2 are the rising and falling time constants, respectively. The peak
location for the pulse is derived using the following formula:
K1 @ k2

Description This is the waveform when a charged capacitor is discharged to the RC
circuit. When the time constants for charging and discharging are taken to
be τ and τ
