[问答题]
In this problem we consider sending real-time voice from Host A to Host B over a packet-switched network( VolP). Host A converts analog voice to a digital 64 kbps bit stream on the fly. Host a then groups the bits into 48-byte packets. There is one link between Host A and B; its transmission rate is 1 Mbps and its propagation delay is 2 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)?
