Humans evolved eating both plant foods and animal foods. By completely eliminating either, we risk becoming deficient in key nutrients. This article lists 7 nutrients that you can not get from commonly consumed plant foods.
PCM redirects here. For other uses, see PCM (disambiguation). Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications. In a PCM stream, the amplitude of the analog signal is sampled regularly at uniform intervals, and each sample is quantized to the nearest value within a range of digital steps.
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.
