The channel capacity for the ideal bandlimited AWGN channel of bandwidth W with two-sided noise power spectral density N₀/2 is given by (1.15). The signal power can be written S = E_bR_t.

Define the spectral bit rate r by

for rates Rt less than capacity. Sketch r as a function of E_b/N₀
expressed in dB.
