Abstract
A random value integration unitoutputs a random value output from a random value generation unitin a diffusion width Rand output from a diffusion width generation unitby a product of an output of the random value generation unitand an output of the diffusion width generation unit. A triangular wave signal generation unitgenerates a triangular wave signal corresponding to a second carrier frequency fcwhich is obtained by adding the random value output from the random value integration unitto a first carrier frequency fcwhich is an output of a carrier frequency setting unit. That is, a frequency obtained by increasing the diffusion width of the first carrier frequency fcis used as the second carrier frequency fc, and the second carrier frequency is used as the carrier frequency.
