White Noise Generator - Is there a chip combining LFSRs and
2024年11月14日 · A bit stream 64 bits long would need to be shifted 8 bits to divide by 64 to get the average output (there is no requirement to divide by 64 because dividing random noise by a constant still equals random noise). The process of converting a bit stream into an analog noise signal could be done very efficiently in the digital realm.
