Therefore, the duration of the signal is determined from the equation A4alt; = ac At ~ 7T. In other ... If a radio station is required to transmit sounds audible to the human ear, then the quantity At is not greater than 0.5 x 10-* sec, since the limit of audibility is 2 x 10* oscillations per sec. ... for distant television transmissions, it is necessary to have either relay stations, very high-placed transmitters, or cable lines.
