In order for a short pulse signal described by the function f(t) to be transmitted through a dispersive medium (medium thickness L) without distortion, it is proposed to form a plane wave disturbance at the entrance to the medium, periodically repeating the signal f(t). The dispersion law of the medium in the signal frequency band has the form k(w) = Bw4. What is the required minimum repetition rate at which an undistorted waveform is repeated at the output of the medium?
