The signal m (t) as shown in figure below is applied both to a phase modulator (with kp as the phase constant) and a frequency modulator with (kf as the frequency constant) having the same carrier frequency(given m(t) maximum amplitude is 2). The ratio kp / kf (in rad/Hz) for the same maximum phase deviation is
