But I didn't. [Chorus] Oh I, I'd done a lot of things different. [Verse 2] I wished I'd a spent more time with my dad when he was alive. Now I don't have the chance. I wish I had told my brother how much I loved him before he went off to war.
Predictive Maintenance (PdM), also known as condition-based maintenance, attempts to evaluate the condition of equipment by performing periodic or continuous (online) equipment condition monitoring.
PDM stands for pulse density modulation. However, it is really better summarized as âoversampled 1-bit. audioâ, as it is nothing more than a high sampling rate, single-bit digital system. If one increased the. sample rate of audio CDs by a large factor, and reduced the wordlength from 16 bits to 1 in a reasonable. way, that would serve as the basis of a PDM system. Most current digital audio systems use multi-bit PCM (pulse code modulation) to represent the signal.
