$5-$ Determine $($a$)$ the peak frequency deviation, $($b$)$ minimum bandwidth, and $($c$)$ Spectral efficiency for a binary FSK signal with a mark frequency of $49$ KHz $,$ a space frequency of $51$ KHz $,$ and an input bit rate of $2$ Kbps $.$

$6-$ Consider a MFSK system with $\backslash (\backslash$mathrm$\{$f$\}\_\{\backslash$mathrm$\{$c$\}\}=150\backslash$mathrm$\{$KHz$\},\backslash$mathrm$\{$f$\}\_\{\backslash$mathrm$\{$d$\}\}=30\backslash$mathrm$\{$KHz$\}\backslash ),$ and $\backslash (\backslash$mathrm$\{$M$\}=8\backslash )($L$=3$ bits$),$

a$)$ Assign each frequency to one of the $8$ possible $3-$bit data combinations.

b$)$ Calculate the bandwidth and the Spectral efficiency,

c$)$ Sketch a time diagram shows the transmitted frequency for the given binary data sequence $101001101010010.$
