Combinatinal Logic and Sequential Logic
=======================================
Combinational logic is a type of digital logic which is implemented by boolean circuits, where the output is a pure function of the present input only. This is in contrast to sequential logic, in which the output depends not only on the present input but also on the history of the input.
3-State Logic
=============
3-State logic allows output ports to assume a high impedance state in addition to the fundamental 0- and 1-levels.
-ve and +ve Logic
=================
Negative logic is just like positive logic, only the desired output is a logic 0 instead of a logic 1
synchronous sequential circuit:
=================================
is a system whose behavior can be defined from the knowledge of its signals at discreet instants of time
asynchronous sequential circuit:
===========================
depends up on the input signals at any instant of time and the order in which the inputs change
