$2.[15$ pts$]$ The normalized message signal mn$($t$)$ has a bandwidth of $5000$ Hz and power of $0\mathrm{.}1$W$,$ and the channel has a bandwidth of $100$ KHz and attenuation of $80$ dB$.$ The noise is white with power$-$spectral density $0\mathrm{.}51012$ W$/$Hz and the transmitter power is $10$ KW$.$ a$.$ If AM with modulation index $0\mathrm{.}8$ is employed what is the output SNR$?$ b$.$ If FM is employed what is the highest possible output SNR$?$
