Abstract
[Task] There is provided a signal generation apparatus and a signal generation method capable of performing mutual switching between a PAM N signal having n values and a PAM M signal having m values (m<n) without generating a noise or an overvoltage. [Means for Resolution] There are provided a PAM N generation circuitthat generates a PAM N signal of n values, a PAM M generation circuitthat generates a PAM M signal of m values (m<n) having a maximum voltage level equal to a maximum voltage level of the PAM N signal generated by the PAM N generation circuit, and a selectorthat outputs any one of the PAM N signal generated by the PAM N generation circuitand the PAM M signal generated by the PAM M generation circuit
