Input signal varies in size, how to get previous values of signal?
1 view (last 30 days)
Br is input signal whose size varies. I need to get this and previous 15 values (Br-1, Br-2...Br-15). I use 15 delay blocks (z^-1) to get 15 previous values. I work fine untill Br varies in size (e.g Br changes from a vector of 256 bits to a vector of 384 bits). Simulink said variable size vector causes the reset of delay block and popup runtime error. Attachment is the design model.
Can we have a solution to get previous 15 values of a variable size signal?

I understand that the issue faced is with delaying a variable sized signal using a unit delay block. You may refer to the blog on Variable-sized signals and unit delay which clearly describes few workarounds for this issue.
Hope this helps!
