- diffhist Pulse-density modulation 18:58 +281 Em3rgent0rdr talk contribs (→Digital-to-analog conversion: "Averaging" is not a useful manner to explain why low-pass filtering works. Instead explain by saying the signal of interest is in a much-lower frequency range and low-pass filtering keeps that while removing the high-frequency noise-shaped quantization noise.)

- diffhist Pulse-density modulation 18:26 +644 Em3rgent0rdr talk contribs (The AN5027 application note that Tllwyd keeps referring to was not relevant to the "Digital-to-analog conversion" section because it is actually talking about PDM-to-PCM conversion, which is a type of *digital-to-digital* conversion. The application note is still useful, but just doesn't belong in that section, so I'm adding a new section "PDM-to-PCM conversion" for it.) Tag: Visual edit

- diffhist Pulse-density modulation 18:13 −512 Em3rgent0rdr talk contribs (Application Note states this is for "PDM to PCM conversion" (section 1.4.3 title), which is a type of digital-to-digital conversion, not digital-to-analog conversion: "In order to convert the PDM stream into ***PCM*** samples, the PDM stream needs to be filtered and decimated."
