A common problem in over-the-air television signal transmission is multipath distortion of the received signal due to the transmitted signal bouncing off structures. Typically a strong main signal arrives at some time and a weaker ghost signal arrives later. So if the transmitted signal is x,() the recieved signal is where >> Kg and 1.x, . 1 What is the transfer function of this communication channel? 2. What would be the transfer function of an equalization system that would compensate for the effects of multipath?

![TF_{sys}=\frac{FT[OP]}{FT[IP]}\\TF_{sys}=\frac{FT[K_mx_t(t-t_m)+K_gx_t(t-t_g]}{FT[x(t)]}\\TF_{sys}=\frac{K_mx_t(\omega)e^{-j\omega t_m}+K_gx_t(\omega)e^{-j\omega t_g}}{x_t(\omega)}\\TF_{sys}=\frac{x_t(\omega)[K_me^{-j\omega t_m}+K_ge^{-j\omega t_g}]}{x_t(\omega)}\\TF_{sys}=K_me^{-j\omega t_m}+K_ge^{-j\omega t_g}](/tpl/images/0518/8500/f6872.png)
