Immediate treatment of heat stroke is body cooling; currently the preferred method of cooling is evaporation cooling by spraying the patient with cold water or covering them with cold water soaked sheets, and using fans to augment evaporative cooling.
Orthogonal Frequency Division Multiplexing or OFDM is a modulation format that is being used for many of the latest wireless and telecommunications standards. OFDM has been adopted in the Wi-Fi arena where the standards like 802.11a, 802.11n, 802.11ac and more.
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. Linear pulse-code modulation (LPCM) is a specific type of PCM where the quantization levels are linearly uniform.This is in contrast to PCM encodings where quantization levels vary as a function of amplitude (as with the A-law algorithm or the Î¼-law algorithm). LPCM has been defined as a part of the DVD (since 1995) and Blu-ray (since 2006) standards. 2  It is also defined as a part of various digital video and audio storage formats (e.g. DV since 1995, AVCHD since 2006).
