Find the difference equation and draw the simulation diagram

1. How do you find the difference equation of a block diagram?
2. How many integrations are required in block diagram?

How do you find the difference equation of a block diagram?

' Difference equation: y[n] = x[n] − x[n − 1] Block diagram: −1 Delay + x[n] y[n] We will exploit particular strengths of each of these representations.

How many integrations are required in block diagram?

In the example above the differential equation is of first order, so we need only one integrator in the block diagram.
