Patent ID: 8436645

Claim:
An information generating apparatus, comprising: a first logic contact, for connecting to a first logic value source; a second logic contact, for connecting to a second logic value source; an information output contact, for outputting a logic information; and a plurality of switches SW (i,j) , wherein SW (i,j) represents a j th switch in an i th layer, 1≦i≦L, 1≦j≦2 (i−1) , and L is an integer equal to or greater than 2 and the number of the switches SW (i,j) of the i th layer is 2 (i−1) , each of the switch SW (i,j) has a first input terminal, a second input terminal and one output terminal, the output terminal of the switch SW (i,j) is selectively connected to the first input terminal or the second input terminal of the switch SW (i,j) , the first input terminals and the second input terminals of the switches SW (L,j) are respectively connected to the first logic contact and the second logic contact, the first input terminal and the second input terminal of the other switch SW (i,j) are respectively connected to the output terminal of the switch SW (i+1,2j−1) and the output terminal of the switch SW (i+1,2j) , and the output terminal of the switch SW (1,1) is connected to the information output contact.
