Transposed Forms A transposed form is achieved by reversing the directions of all branches while keeping the branch coefficients the same. Of course, by doing that, the roles of the input and output signals will be reversed as well. The system function of a transposed form is identical to that of the original system. Summary 11 – p. 2/

Unformatted text preview: form. We can add first and multiply second to keep the properties of the linear-phase FIR systems. Summary 11 – p. 3/ 4 Feedback The IIR systems do need certain kinds of feedback. However, a signal flow graph with feedback is not necessarily an IIR system. The key to computability of a flow graph is that all loops must contain at least one unit delay element (avoid delay-free loops). Summary 11 – p. 4/ 4...

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
