Implementation Details
The power meter measures the average power of the input signal. Please see the example file PWM.icp for more information on this element. The following figure shows the system in the example file.
There are two types of input signals in the system, one DC source and one AC source. The power meters measure the average power of the two signals. The following figures show the measured results of the two electrical sources, respectively.
