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.
PCM vs Bit Stream. Pulse Code Modulation digitally signifies an analogue signal. This signal is sampled regularly at precise intervals. This signal is then quantized into numeric coding, usually binary coding. PCM is most usually found in telephone systems, keyboard pianos dating back to the 1980âs, audio found in computers, CD âred bookâ formats, and digital video. Bit stream is, basically, a time series of bits.
