How many propagation delays are needed to implement an arbit
     How many propagation delays are needed to implement an arbitrary (unminimized) Boolean function using AND, OR, and Inverter gates?  3  It depends on the number of rows in the truth table.  It depends on the number of OR gates.  It depends on the number of AND gates.  It depends on the number of input variables. 
  
  Solution
Answer:
E) It depends on the number of input variables
explanation:
A logic gate truth table shows each possible input combination to the gate or circuit with the resultant output depending upon the combination of these inputs.
