Question : (4 marks) uni Compare Nkz and RZ signaling techniques in term and RZ signaling techniques in terms of probability of a bit error P[e]. The bit rate R-1/T and pulse amplitude a are fixed. Ketch the curve of energy-to-noise ratio E/N. (dB) versus probability of P[e] Hint: The energy of an RZ pulse is one half that of an NRZ pulse.) hould the rate R be modified in the case of RZ signaling so that its P[e) is the same as IVA NRZ signaling?
