distortionless การใช้

• A bonus was a distortionless top speed of 1 / 4000 s ( with 1.7 mm slit ).
• In terms of primary coefficients of the line, this yields from the telegrapher's equation for a distortionless line the condition
• For a line meeting the distortionless condition, with a conductance " G " in the insulator, the attenuation constant is given by
• Which has to be of the form \ scriptstyle ( A + j \ omega B ) ^ 2 in order to meet the distortionless condition.
• This is not identical to a distributed loading, the difference being that with loading coils there is distortionless transmission up to a definite cut-off frequency beyond which the attenuation increases rapidly.
• Petzval's portrait objective lens ( " Petzval Portr鋞objektiv " ) was an almost distortionless " Anachromatischer vierlinser " ( double achromatic objective lens, with four lenses in three groups ).
• I'm looking for a simple formula to allow perspective correct interpolated 2D screen cordinates to be calculated for given 2D texture coordinates, given that a 3D projection, distortionless camera is looking at a plane.
• The most famous example is the Rapid Rectilinear Lens developed by John Henry Dallmeyer in 1866 . it allowed distortionless photos to be taken quickly for the first time, and was a standard lens design for 60 years.
• Campbell was aware of Heaviside's work in discovering the Heaviside condition, in which the specification for distortionless transmission of signals is formulated, but apparently was not aware of Heaviside's suggestion of using loading coils to force a line to meet it.
