critical frequency वाक्य

उदाहरण वाक्य

1. On a given day, communications may or may not succeed at the MUF . Commonly, the optimal operating frequency for a given path is estimated at 80 to 90 % of the MUF . As a rule of thumb the MUF is approximately 3 times the critical frequency.
2. The Wobbulator generator, designated model 1200A, combined sweep and marker functions into a single self-contained pushbutton-controlled device which, when connected to an oscilloscope and television receiver under test, would display a representation of the receiver's RF / IF response curves with " markers " defining critical frequency reference points as a response curve on the oscilloscope screen.
3. He found that a representative worldwide relationship for the 1949 1959 solar cycle, is given, by N _ M ( E ) = k _ 1 ( f _ 0 E ) ^ 2 = k _ 2 ( 1 + 0.00334R ) where f _ 0 E is the critical frequency of the Heaviside layer and k _ 1, k _ 2 are constants.
4. Later in 1974 together they went on to conduct a statistical investigation of the variation of E-region critical frequency f _ 0 E with solar activity, solar zenith angle and season, to obtain a describing function of f _ 0 E in terms of geographic latitude, solar zenith angle and 10.7 cm solar radio-noise flux, for the design of ionospheric transmission paths.
5. There will be 5 MHz?0 ms = 50, 000 samples in the digital signal, and therefore 25, 001 frequency components ranging from 0 Hz to 2.5 MHz in steps of 100 Hz ( note that the 0 Hz component is real because it is the average of a real-valued signal and the 2.5 MHz component is real as well because it is the critical frequency ).
