R Robby23 New Member Jun 6, 2010 #1 Hey. I need to find the differential equation expressed by this block diagram. Can anyone help me? I can't seem to figure it out. Thanks in advance. picture attached to post also for whoever helps me out could you please show me in steps how to do it so I can figure out what I am doing wrong. Thanks Attachments 001.jpg 77 KB · Views: 200 Last edited: Jun 6, 2010

R Robby23 New Member Jun 6, 2010 #3 ok I understand that but how would I get rid of the integral of y(t)? Is there a way to eliminate all integrals from the answer? cuz you get Y(t)=(5X(t) - 5Y(t) + 15∫Y(t) )+ (∫ (X(t) - Y(t) + 3∫Y(t))) then what Last edited: Jun 6, 2010
