Why Divide and Conquer

It is tough break a bunch of sticks that tied together (it is tough to solve all aspect of design requirements one-shot):

But if we divide the bunch of stick to individual stick or smaller bunch of sticks, each stick or small bunch of stick is easier to break than before.

It is always tough to solve complicated circuit without breaking the circuit into manageable blocks. Building and testing of each block by itself and combine them into final solution is the systematic way of solving complicated task. It is called applying "divide and conquer" strategy.


The key is to know how to break the complicated design requirements into manageable pieces – and to do this we need to understanding loading, and to understand concept of output and input impedance of each circuit block.
