摘要：A switching device for switching between a 1-bit digital signal ΣΔ modulated bya first sampling frequency and a 1-bit digital signal ΣΔ modulated by a second samplingfrequency lower than said first sampling frequency. The 1-bit digital signal ΣΔ modulated
by the second sampling frequency is transiently converted to the 1-bit digital signal ΣΔmodulated by the first sampling frequency. The converted 1-bit digital signal or the 1-bitdigital signal ΣΔ modulated by the first sampling frequency is switched by cross-fadingprocessing for realizing switching with suppressed noise generation at the time ofswitching.
