Find Magnitude and Phase of Sinusoidal Waveforms in Simulink

I am inputting three sinusoidal signals from sensors to the ADC of an eZdsp that I am programming with Simulink. Each of these are 60 Hz waveforms (These are not voltages of a power system, the phases are not 120 degrees apart).

I need to use Simulink to determine the magnitude and phase of all three of these waveforms with respect to each other. I understand that there is a block in the SimPowerSystems library that outputs the magnitude and phase of three-phase voltages or currents. I do not have access to this library, but I would like to implement similar functionality on my own.

Any assistance in this matter will be greatly appreciated. Thanks. Start a New Thread
