b$)$ We have four sources, each creating $2\mathrm{.}50$ characters per sccond. If the interleaved unit is a character and I synchronizing bit is added to each frame, calculate the following:

$($i$)$ Data rate of each source

$($ii$)$ Duration of each character in each source

$[2$ Marks$]$

$($iii$)$ Frame rate

$[2$ Marks$]$

$($iv$)$ Duration of each frame

$[2$ Marks$]$

$($v$)$ Number of bits in each frame

$[2$ Marks$]$

$($vi$)$ Data rate of the link.

$[2$ Marks$]$

$[3$ Marks$]$
