Sinusoidal Pulse

General Form:
spulse(vo vp [per td decay])
Example:
vin 1 0 spulse(0 1 25ns 40ns 1e8)

parameter description default value units
vo offset   volts or amps
vp peak amplitude   volts or amps
per period tstop seconds
td delay 0.0 seconds
decay decay const 0.0 1/seconds

The shape of the waveform is described by the following table:

time value
0 vo
td vo + 0.5 . (vp- vo)( 1 - cos(2$ \pi$ . (time- td)/per) . exp(- (time- td) . decay) )

This function applies only to transient analysis, where time is the running variable. When referring to default values, tstep is the printing increment and tstop is the final time in transient analysis, see 2.7.9 for explanation.
