The Hamming encoder/decoder in the lecture detected and corrected one error bit. By adding a thirteen bit which is the exclusive-OR of the other twelve bits, double bit errors can be detected (but not corrected). Add this feature to the example and modify the noisy channel so that sometimes two bits are in error. Change the $display statement to indicate the double error. See the additional supplemental information about the 13-bit Hamming code. Please show all the Verilog codes for your design.
