| 摘要 | . A noise generating device is provided which includes a pseudo-random number generator having a shift register that performs shift operations to sequentially shift the bit in the input stage to the next higher significant stage and an exclusive-OR circuit that XORs a plurality of bits from selected stages of the shift register and feeds back to the first stage of the shift register, and an analog filter having an analog element that limits the band of digital data created from the bits in the shift register of the pseudo-random generator and outputs as an analog signal. | ||||||
