Over a period of time these frequencies and their associated letter-band designations have been fixed by usage. In order to recognize and preserve accepted usage, this standard defines the letter-band nomenclature to be used as a convenience for describing the frequency in which radar operates. It should be cautioned that these are not a substitute for the specific frequency limits of a radar, nor is it meant that these letter bands be applied to other than radar.IEEE Std 521-1976Tracking radarRadarInterferenceTracking radar.RadarInterference.621.3848NjHacINjHaclDOCUMENT9910136386603321IEEE Std 521-19763646202UNINA01228nam0 22003133i 450 VAN010215820230512115202.133N978884702053520150713d2012 |0itac50 baitaIT|||| |||||Storia della logopediaIrene Vernero, Oskar SchindlerMilano : Springer, 2012X82 p. ; 24 cm001VAN01020682001 Metodologie Riabilitative in Logopedia210 MilanoSpringer2005-.22MilanoVANL000284VerneroIreneVANV079709323938SchindlerOskarVANV079710469932Springer <editore>VANV108073650ITSOL20240614RICAhttp://link.springer.com/book/10.1007/978-88-470-2053-5E-book – Accesso al full-text attraverso riconoscimento IP di Ateneo, proxy e/o ShibbolethBIBLIOTECA CENTRO DI SERVIZIO SBAVAN15NVAN0102158BIBLIOTECA CENTRO DI SERVIZIO SBA15CONS SBA EBOOK 262 15EB 262 20150713 Storia della logopedia1410978UNICAMPANIA
