Mode 2 is used to identify military aircraft missions. Mode 3/A is used to identify each aircraft in the radar's coverage area. Mode C is used to request/report an aircraft's altitude. Two other modes, mode 4 and mode S, are not considered part of the ATCRBS system, but they use the same transmit and receive hardware.
It simply means how many transponders would be used if the same total bandwidths used only 36 MHz transponders. [ 3 ] [ 4 ] [ 5 ] So, for example, the ARSAT-1 has 24 IEEE K u band transponders: 12 with a bandwidth of 36 MHz, 8 with 54 MHz, and 4 with 72 MHz, which totals to 1152 MHz, or 32 TPE (i.e., 1152 MHz divided by 36 MHz).
ReplayGain is a proposed technical standard published by David Robinson in 2001 to measure and normalize the perceived loudness of audio in computer audio formats such as MP3 and Ogg Vorbis.
In 1981, the FAA decided to implement the Traffic Alert and Collision Avoidance System (TCAS), which was developed based on industry and agency efforts in the field of beacon-based collision avoidance systems and air-to-air discrete address communication techniques that used Mode S airborne transponder message formats.
The C band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 4.0 to 8.0 gigahertz (GHz). [1] However, the U.S. Federal Communications Commission C band proceeding and auction, designated 3.7–4.2 GHz as C band. [2]
A lossless audio coding format reduces the total data needed to represent a sound but can be de-coded to its original, uncompressed form. A lossy audio coding format additionally reduces the bit resolution of the sound on top of compression, which results in far less data at the cost of irretrievably lost information.
Along with albums, digital albums, and singles there is another classification of music release called "Video Longform." This release format includes DVD and VHS releases, and certain live albums and compilation albums. The certification criteria are slightly different from other styles. [27] [28] Gold: 50,000 copies; Platinum: 100,000 copies
An implantable RFID tag or transponder can also be used for animal identification. The transponders are better known as PIT (Passive Integrated Transponder) tags, passive RFID, or "chips" on animals. [70] The Canadian Cattle Identification Agency began using RFID tags as a replacement for barcode tags.
