Which statement is true about the difference between combina
     Which statement is true about the difference between combinational logic circuits and sequential logic circuits?  If you know the values of the inputs to a combinational circuit, you can tell what the outputs must be, but a sequential circuit can have different outputs for the same set of input values.  Combinational circuits combine the inputs and the outputs, but sequential circuits combine the outputs only after generating the inputs.  Combinational circuits are more complicated than sequential circuits.  Combinational circuits have feedback, but sequential circuits do not.  Combinational circuits are edge triggered, but sequential circuits are level-sensitive. 
  
  Solution
The first statement is true about combinational and sequential circuit.
Combinational circuit output depends only on the input whereas in sequntial circuit output depends on input and state which is calculated by clock.
