Applied Course | Mock GATE | Test 1 | Question: 64
Let us consider a scenario of sending real-time voice from Host A to Host B over a packet-switched network. Host A converts analog voice to a digital $32$ kbps bit stream on the fly. Host A then groups the bits into $44$-byte packets. There is one link ... bit is decoded (as part of the analog signal at Host B)? $11$ ms $88$ ms $30$ ms $30.088$ ms
