Can someone confirm if this is the correct block diagram for the following transfer function?

The original equation provided was: y[n+1] = y[n] + 0.01x[n]

Which I rearranged into H(z) = Y(z)/X(z) = 0.01 / (z - 1) and then also rearranged into y(n) = y(n-1) + 0.01x(n-1)

And left me with the following block diagram,

  • $\begingroup$ The second z^-1 block should be multiplied with -1 $\endgroup$ – DSP Novice Mar 14 '20 at 4:13
  • $\begingroup$ The loop is already traveling in the reverse direction, thus accounting for the y(n-1) in my given equation. $\endgroup$ – Liam Mar 14 '20 at 7:19
  • $\begingroup$ Oh yeah...thats right ! My bad. I solved it again and I got the same as yours. $\endgroup$ – DSP Novice Mar 14 '20 at 9:28

That is a correct way to do it, but leaves you with (depending on what you're trying to do) an excess of delay blocks. This also works:
