Why is Electrical length greater than physical length?

WebNote that the very first dip is where the cable is less than 1/4 wavelength. From then on the dips occur when the cable is an odd number of quarterwaves, or the distance between each dip is caused by an additional half-wave. The distance between the first two dips (deltaF) is 99 MHz. Plugging this into the equation we calculate the cable length ... WebFor example, if the transmission line length is equal to one wavelength long, you'd specify the electrical length as \$360^\circ\$. But ADS will assume the physical length of the … interrupt crossword

WebFeb 12, 2016 · This is shown below at \$500\mathrm{MHz}\$, but the frequency is only important when converting the electrical length to a physical length. What a quarter wave transformer does is rotate a given point by \$180^\circ\$ around its characteristic impedance on the Smith chart (that's \$\lambda/4 = 90^\circ\$ forward plus \$90^\circ\$ reverse). WebLet us understand this in detail below. Electrical length =E= (l/Lambda ref) * 360 degree. E= T * F ref * 360 degree. This indicates that a line which is 1 ns long has an electrical length (E) of about 360 degree at frequency (F ref ) of 1GHz.
