| + | ====== Single-Frequency FM ====== | ||
| + | In this section we will show indipendent **Single-Frequency FM source**. It has this general form;\\ \\ | ||
| + | ''sffm(Vo Va Fc Mi Fs)'' \\ \\ | ||
| + | where the model parameters are shown in the below table: | ||
| + | ^ Parameters ^ Default value ^ Unit ^ | ||
| + | | **Vo** (offset) | | **A**mpere or **V**olt | | ||
| + | | **Va** (amplitude) | | **A**mpere or **V**olt | | ||
| + | | **Fc** (carrier frequency) | 1/Tstop | **Hz** (Hertz) | | ||
| + | | **Mi** (modulation index) | | | | ||
| + | | **Fs** (modulation frequency) | 1/Tstop | **Hz** (Hertz) | | ||
| + | The Single-Frequency FM (SFFM) form causes that the shape of the waveform is described by the following equation:\\ \\ | ||
| + | ''v(t)=Vo+Va*sin[(2π*Fc*t)+Mi*sin(2π*Fs*t)]''\\ \\ | ||
| + | For example;\\ \\ | ||
| + | ''V1 1 0 sffm(2 24 10k 5 1k)''\\ \\ | ||
