$($d$)$ Data is transmitted asynchronously using bits of $20mS$ duration. The receiver clock is operating at $48Hz.$ Determine the:

$($i$)$ receiver clock period; $\frac{1}{x}\frac{1}{42}=0\mathrm{.}02083$

$($ii$)$ slip in receiver clock on each successive bit; $960$

$($iii$)$ number of slips for the receiver to slide beyond half of the received bit period. $(8$ marks$)$
