This function can be called as tsin to avoid possible conflict with the sin math function.
parameter description default value units vo offset volts or amps va amplitude volts or amps freq frequency 1/tstop hz td delay 0.0 seconds theta damping factor 0.0 1/seconds phi phase delay 0.0 degrees
The shape of the waveform is described by the following table:
time value 0 to td vo + va . sin( . phi/180) td to tstop vo + va . exp(- (time- td) . theta) . sin(2 . (freq . (time- td) + . phi/360 ))
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. The argument count is used to distinguish this function from the math function of the same name.
