Changing Phase of a signal

This is the similar situation i am facing..

I have a sine block and i use the sine wave to feed it to another block...Now if i want the same sine block to be the input to another block but the sine wave being phase shifted by 180 degrees..Is there any block in simulink to do it..

Overall i just want 2 outputs from a sine block 1)the same sine wave 2)other wave,phase shifted by 180 degrees

Please help me...

Hi,

you could put into the phase entry the vector [0 180], then you will get a two component vector as output signal. Use either selector or demultiplexer to split into individual signals.

Nice to know!

Thank you very much....

how do u do that ?? [0 180]? where do you specify it?

Certainly you can do this with two sine wave blocks, but I guess you are not looking for this solution. What I am trying to say is that you can think about it in a physical world. If you can only see the value of a signal coming, you want to shift it with 180 degrees phase. It's not a simple task. I don't know any readily available Simulink block can do that.
