Q$\mathrm{.}2)$ In this problem, we consider sending real$-$time voice from Host A to Host B over a packetswitched network $($VolP$).$ Host A converts analog voice to a digital $64kbps$ bit stream on the fly. Host A then groups the bits into $56-$byte packets. There is one link between Hosts A and B; its transmission rate is $2Mbps$ and its propagation delay is $10$msec. As soon as Host A gathers a packet, it sends it to Host B$.$ As soon as Host B receives an entire packet, it converts the packet's bits to an analog signal. How much time elapses from the time a bit is created $($from the original analog signal at Host A$)$ until the bit is decoded $($as part of the analog signal at Host B$)?$
