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.
In the digital domain, PCM (P ulse C ode M odulation) is the most straightforward mechanism to store audio. The analog audio is sampled in accordance with the Nyquest theorem and the individual samples are stored sequentially in binary format. The wave file is the most common format for storing PCM data. But, before you dig into the internals of wave files, it would help to get some insights to the Interchange Format Files that form the basis for the wave file format.
