Problem with samples

Hi,

I am working with simulink and There is a row in an array that sends out data in the following manner. [1,3,4,5,21,3,1,2,4,2,3,2,23,23,3,4,2].

I would like to analyze 5 elements at once. When i keep samples per frame = 5, output is [1,3,4,5,21] [3,1,2,4,2] [3,2,23,23,3] [4,2,...]

but I am actually looking to analyze them in the following manner.

[1,3,4,5,21] [4,5,21,3,1] [21,3,1,2,4] [2,4,2,3,2] [3,2,23,23] [23,23,3,4,2]

Is there a way to do this? Please let me know. Thank you.

Looks like you need to buffer with a size of 5 and overlap of 3.

It is this Buffer block from the DSP System toolbox.

Hello Rouleau,

Thanks for the reply. I am relatively new to the Simulink. Could you please elaborate your answer? How can I overlap? I see that there is a Overlap-ADD FFT filter in the simulink. Were you pointing to some like this? Thanks again.

[Fangjun Jiang]

Set the buffer size and overlap at the dialog window of the Buffer block.

Thank you so much.
