How do you find the impulse response from a difference equation?

Given the system equation, you can find the impulse response just by feeding x[n] = δ[n] into the system.

What are the advantages of block diagram representation of discrete time systems?

Advantages of block diagram representation: Easy to write down the computational algorithm (explicit relation between the output and input) by inspection. Easy to manipulate a block diagram to derive other “equivalent” block diagrams yielding different computational algorithms.
