• curprev 19:0719:07, 23 August 2023‎ Em3rgent0rdr talk contribs‎ 9,298 bytes −78‎ →‎Operation: Slight tweaking for correctness: The "quantization error between the quantized value and the original value" is not correct. There is a continued feedback, y[n] is not "the original value" so the quantization is not between "the original value". Avoiding word "stored" because it is not a long term storage here, just a single cycle, so measured suffices. And better not say "its quantization" cause it is not the input sample alone being quantized but the sum with the prior error. undo Tag: Visual edit
