Errata for the book 
Verilog Designer's Library
	- Page 101, the fourth sentence should read "In other words, in a Mealy 
	machine..."
 
Thanks to Carl R. Martin and R. Rana for finding the following errata. 
    - Page 22, figure 3-6 change signal SIG2a to SIG2d
 
	- Page 23, in the code at the top change "sig2d <= sig;" to "sig2d 
    <= sig2;"
 
	- Page 24, the code to implement the circuit in Figure 3-8 should be:
 
		assign z = a1 & ~a2;
		always @(posedge clk) begin
			a1 <= a;
			a2 <= a1;
		end
  - Page 29, Figure 3-15, output of flip-flop should be labeled Q instead of 
    1
