I was making a circuit to generate voltage sag signal as shown in the image in the link below: http://img830.imageshack.us/img830/5792/matlab.jpg
As you can see in the oscilloscope, there are two signals instead of one signal generated when I was trying to combine one sine wave signal with one step input. It is a product of a sine wave and a step input so supposed the answer should be only one signal. The mdl file can be downloaded here. Please advised. Much appreciated.

It's the step block that's generation the extra signal, I'm trying to find a fix for it, please wait
A way to fix it is to put a demux block in the output of the Product block and a Add block to add the demux outputs together, hope this helps.
