19. An acoustic signal, having the power spectral density given in the form: So :f≤ f S)(f)=1+ f f₂ :f> f is the message signal in the FM system. Find the gain factor k and limit frequency f₁ of the pre-emphasis filter and the noise reduction factor. Assume, that the frequency fi is a 3 dB frequency of the power spectral density Smo (5).
