In this problem, we consider sending voice from Host A to Host B over a direct link network (for example, Internet phone). Host A converts analog voice to a digital 64Kbps bit stream on the fly. Host A then groups the bits into 128-byte packets. There is one link between Host A and Host B; its bandwidth is 1Mbps and its propagation delay is 30 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 packets bits to 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)
