Abstract: Practical methods for making laboratory measurements of electroacoustic characteristics of analog and digital telephones, handsets, and headsets are presented. The methods may also be applicable to a wide variety of other communications equipment, including cordless, wireless, and mobile communications devices. Measurement results may be used to evaluate these devices on a standardized basis. Application is in the frequency range from 100 Hz to 8500 Hz. Keywords: analog telephones, digital telephones, electroacoustic measurements on telephones, handsets, headsets, IEEE 269, IEEE 269a, telephony, voice transmission performance. |

Sommario/riassunto |
|
Drawing on political oratory, diplomatic correspondence, crusade propaganda, and historical treatises, Meserve shows how research into the origins of Islamic empires sprang from-and contributed to-contemporary debates over the threat of Islamic expansion in the Mediterranean. This groundbreaking book offers new insights into Renaissance humanist scholarship and long-standing European debates over the relationship between Christianity and Islam. |
