Single-frequency FM

SFFM(VO VA FC MDI FS)

Example:

V1 12 0 SFFM(0 1M 20K 5 1K)
VNEW 1 0 SFFM(0 1m 50MEG 4 10MEG)

 

Single-frequency FM (SFFM) Parameters

Name Meaning Units Default
FC carrier frequency Hz 1/TSTOP
FS signal frequency Hz 1/TSTOP
MDI modulation index
VA amplitude V or A
VO offset V or A

 

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

value= VO+VA*sin((2*FC*time)+MDI*sin(2*FS*time) )
