This is the rising and falling exponential function pulse. Made with the equation
editor.

Constants k1 and k2 are the rising and falling time constants, respectively. The peak
location for the pulse is derived using the following formula:

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 τ1 and τ2, respectively, the waveform can be expressed by the following
