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.
Differential pulse code modulation or Delta pulse code modulation (DPCM) is a technique in which PCM values are encoded as the difference between the current and previous values. In audio formats, this type of encoding reduces the number of bits required per sample by about 25% compared with PCM.
