In a facsimile receiver, the device that performs the final conversion of the facsimile picture signal to an image of the object, i.e., makes the recorded copy.
Industry:Telecommunications
In a facsimile receiver, the dimension that (a) is perpendicular to a scanning line and (b) is the smallest recognizable detail of the image produced by the shortest signal capable of actuating the facsimile receiver under specified conditions.
Industry:Telecommunications
In a facsimile recorder, the spot that is used to generate the recorded copy on the record medium.
Industry:Telecommunications
In a facsimile system, a measure of the light transmission or reflection properties of an area of an object. Note 1: Density is usually expressed as the logarithm to the base 10 of the ratio of incident to transmitted or reflected irradiance. Note 2: There are many types of density, such as diffuse, double diffuse, and specular density, each of which will usually have different numerical values for different materials. The relevant type of density depends on the type of optical system, the component materials of the object, and the surface characteristics of the object. 2. In video, the degree of darkness of an image, or the percent of the screen used in an image. 3. In optics, a figure of merit that describes the degree of attenuation introduced by a filter.
Industry:Telecommunications
In a facsimile system, the equipment that converts the baseband picture signals, i.e., the baseband signals resulting from scanning the object, into signals suitable for transmission by a communications system.
Industry:Telecommunications
In a facsimile system, the equipment that converts the facsimile picture signal into a recorded copy.
Industry:Telecommunications
In a facsimile system, the equipment that sends and receives facsimile signals. Note: Full-duplex facsimile transceivers can send and receive at the same time; half-duplex facsimile transceivers cannot.
Industry:Telecommunications
In a facsimile system, the signal level at any point in the system. Note 1: The facsimile signal level is used to establish the operating levels. Note 2: The facsimile signal level is usually expressed in dB with respect to some standard value, such as 1 mW (milliwatt,) i.e., 0 dBm.
Industry:Telecommunications
In a facsimile system, the smallest discrete scanning line sample containing only monochrome information, i.e., not containing gray-scale information.
Industry:Telecommunications
In a facsimile transmission system, the highest picture frequency that is required. Note: The maximum modulating frequency and the maximum keying frequency are not necessarily equal.
