Abstract
In a signal generating device, first signal generation meansfor generating a most significant bit signal stream MSB, second signal generation meansfor generating a least significant bit signal stream LSB, a mask generation meansfor defining a bit that allows error insertion and a bit that prohibits error insertion with different pieces of bit information, and generating a mask pattern of each of the most significant bit signal stream MSB and the least significant bit signal stream LSB, based on symbol transition information indicating a transition destination of four PAM4 symbols of a PAM4 signal; and error insertion meansfor inserting an error, based on bit information of the mask pattern corresponding to each bit of the most significant bit signal stream and the least significant bit signal stream designated according to a symbol error rate.
