Largo de los Cables Coaxiles
We can calculate the length of the coaxial cable that we are going to use. It is long, it is determined in a quarter wave, this is due to the fact that the impedance of the antenna must be adjusted to the cable to be used and the radio

Measurements on Balanced Lines
Over the years, distortion in amplifiers and other electronic devices has been measured by many different techniques
