In a driver circuit 10 for outputting a simulated signal simulating an input signal subjected to transmission loss, corresponding to the input signal, the driver circuit 10 comprises: a main driver 18 which receives the input signal and outputs an output signal corresponding to the input signal; a sub driver 20 which receives the input signal and outputs an output signal given by inverting the input signal; a high frequency emphasizing circuit 22 which receives the input signal of the sub driver 20 and outputs an output signal having the high frequency of the input signal of the sub driver 20 emphasized; and an addition unit 24 which outputs the simulated signal given by adding the output signal of the main driver 18 and the output signal of the high frequency emphasizing circuit 22.
