Is Arduino can do FM modulation?

Is Arduino can do FM modulation without any additional peripherals.Simply an Higher AC frequency signal with antenna can propagate in air. My question is,can we do FM modulation in Arduino only by coding it,without using any additional peripherals.Generating the carrier frequency in Arduino by coding it and then by performing FM modulation by coding it,getting the external audio signal through Analog input pins and after all the modulation process, connecting a long wire on the digital pin of arduino because the square wave is going to be used as carrier signal.A simple wire can act as a Antenna.Is the above explained process is possible in Arduino only by programming it.
