Note: Front-to-back ratio is usually expressed in dB. 2. A ratio of parameters used to characterize rectifiers or other devices, in which electrical current, signal strength, resistance, or other parameters, in one direction is compared with that in the opposite direction.
Industry:Telecommunications
1. Of a periodic signal, pertaining to transmission in which the time interval separating any two corresponding transitions is equal to the unit interval or to a multiple of the unit interval. 2. Pertaining to data transmission in which corresponding significant instants of two or more sequential signals have a constant phase relationship. Note: "Isochronous" and "anisochronous" are characteristics, while "synchronous" and "asynchronous" are relationships.

1. Measures and controls taken to deny unauthorized persons information derived from telecommunications and to ensure the authenticity of such telecommunications. Note: Communications security includes cryptosecurity, transmission security, emission security, and physical security of COMSEC material. • (a) cryptosecurity: The component of communications security that results from the provision of technically sound cryptosystems and their proper use. • (b) emission security: Protection resulting from all measures taken to deny unauthorized persons information of value which might be derived from intercept and analysis of compromising emanations from crypto-equipment, AIS, and telecommunications systems. • (c) physical security: The component of communications security that results from all physical measures necessary to safeguard classified equipment, material, and documents from access thereto or observation thereof by unauthorized persons. • (d) transmission security: The component of communications security that results from the application of measures designed to protect transmissions from interception and exploitation by means other than cryptanalysis. 2. Measures to ensure the confidentiality and integrity of information in telecommunications systems and channels. See also: Electronic Information Systems Security.
