Whatis the end-to-end error probability?3- Numerous bandwidth definitions have been devised, such as the 3-dB bandwidth, the I -dBbandwidth, the noise bandwidth, etc. Explain these definitions (a sketch would help understandingthe concepts). Also, explain why these bandwidths cannot be converted from one to another by simpleformulas.What additional infonnation isneeded to convert from one bandwidth to another?4- Explain why the tolerable channel noise level decreases as the number of modulation levelsincreases, assuming the bit error probability is to be held constant.5- Why can a 9.6 kilobaud transmiss ion rate not be sent over a voice bandwidth line? What is the maximum rate according to the sampling theorem?6- Explain why digital techniques at baseband appear to exhibit twice as much spectral efficiency(bis per Hz) as techniques involving the modulation of a digital waveform on a carrier.
