It specifies the implementation of the physical layer for wireless UNII b. An international IEEE standard for WLAN networks, operating at 2. 4GHz and providing a maximum data transfer rate of 11Mbps. A proposed standard that describes a wireless networking method for a WLAN that operates in the 2. It transfers data at up to 54Mbps.
A-weighting is a standard weighting curve applied to audio measurements, designed to reflect the response of the human ear. Sound-pressure levels derived using A-weighting are denoted by “dBA,” or A-weighted dB levels. D converter, a circuit that converts analog signals into a stream of digital data. A sensor or transducer for measuring acceleration. Adaptive Differential Pulse Code Modulation: A compression technique that encodes only the difference between sequential samples.
