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.
The resultant bitstream can be stored as files on a computer in a variety of formats, including WAV, FLAC, AIF, or M4A files. There are several other uncompressed PCM file formats, but the first three formats (WAV, FLAC, and AIF) can be played by all of the high-end music players Iâve tried. DSD, on the other hand, uses a much higher sampling rate, 2.8224MHz, or 2,822,400 samples per second.
