# How to shift signal phase in matlab from this circuit?

The circuit shown is in matlab. Sinus signal is provided by vpin by connecting from PCI. The sinus signal is looks like on the scope. The problem is i want to shift signal phase, from the picture below is circuit needed to shift the sinus signal phase, but there's a red dot that i can't connect the shift circuit (R-C) with my sinus to shift signal phase... How to solve this? Is there any way to shift the signal phase?

• Is there an EE question lurking here or is it just about how to use MATLAB? – Andy aka Jul 26 '16 at 13:03
• Add a transfer function block for the RC network. Or, a pure time delay block with delay, $\small T$, will give a phase lag of $\small \omega T$ rad without affecting the gain. – Chu Jul 26 '16 at 13:18

If however you are after a more electrical affect then a suitable transfer function $\frac{1}{1+\tau s}$ would produce an equivalent electrical response while residing within the S-domain/Simulink
