Interesting, berk, i guess this is invoking another question, is the radius of pole shows some similar relation with the magnitude response?

You did wrong while expanding and simplifying

use MATLAB, you can find functions for direct FIR designing using Remez Exchange Algorithm or using different Windows.

An FIR filter for example H(z)= 1+h(0)/z + h(1)/z*z + h(2)/z*z*z, has length 4 and order 3.

I think the problem is in the index of datastruct, as it is showing. May be the length of data_filtered is not the same as datastruct. It is very common problem occurs in MATLAB. For Example : if H=[1:5]; and then Y=[1:7]; and if you do H=Y(15); then it occurs. Hope it is helpful

Yes Dear, a system in DSP can be a filter, and a filter can be use for different types of processing of signal in digital domain. A filter is always represented by a system function in z-transform. Some filters can be just anti-aliasing, while some can be differentiators or integrators. I think...

Thanks!

Dear Friends, Some one can help me to make sedumi function which can solve the semidefinite optimization. Additionally, how can I distinguish between Second order cone programming and semidefinite quadratic linear programming. Thank You.
