Hello! I would like to ask if anyone has tried simulating an FM modulator in Multisim NI since we have been trying for hours and none of the examples online seems to work. We were specifically targeting a waveform like this once we’ve used an oscilloscope, but each time it has been an FSK modulator, some sort of AM, or just a dead straight line with noise once zoomed incredibly close. We were told that using a XR2206 IC works but it is not officially supported on multisim (we tried importing from a forum but it doesn’t work either). Using the 555 timer gave us FSK and we can’t transfer it back to a regular sine wave. It would be a huge help if anyone got a guide or circuit design we could follow as we’re really struggling. thank you so much!
