labview FM频率调制

PURPOSE: To build a Virtual Instrument to simulate a Frequency Modulated Carrier Signal. DISCUSSION: FM is another form of angle modulation. The signal is expressed in the following form, In this simple example, we can carry out the simulation a lot easier if we first perform the integration required in the phase angle. The result is, Now using this final FM signal expression, a LabVIEW Front Panel as shown below can easily be build.
