[[RF.Spice]]'s FM modulator takes an arbitrary input signal and generates a frequency-modulated sinusoidal signal at its output.

To generate a binary sequence for this project, , you will use a "Digital Source" followed by a DAC conversion bridge. The data rate will be 1GHz or 1G sample/s. In other words, we assume a clock rate of 1GHz with a period of 1ns and a pulse with of 500ps, The input binary sequence is:
