Recalling two FEC schemes for internet phone described. Suppose the first scheme generates a redundant chunk for every four original chunks. Suppose the second scheme uses a low-rate encoding whose transmission rate is 25 percent of the transmission rate of the nominal stream.
a) How much additional bandwidth does each scheme require? How much playback delay does each scheme add?b) How doe the two schemes perform if the first packet is lost in every group of five packets? Which scheme will have better audio quality?c) How doe the two schemes perform if the first packet is lost in every group of two packets? Which scheme will have better audio quality?

What is ipconfig? Ipconfig is a utility program that is commonly used to recognize the addresses information of a computer on a network. It can show the physical address as wel
Butterfly permutation This permutation is getting by interchanging the important significant bit in address with smallest significant bit.
In quantum computing, we use the method of qubits, superposition and coherence. A normal bit can be in only two states - 0 and 1. But a qubit it can be in 0, 1, or in the superposi
