Suppose N₀ = 10^-6 W/Hz and the base band data bandwidth is given by B = R = 1 / T Hz.

For the Required Signal Power A² and Bandwidth

R, bps P_E = 10^-3 P_E = 10^-4 P_E = 10^-4 P_E = 10^-5 P_E = 10^-6

1,000

10,000

100,000

following bandwidths, find the required signal powers, A², to give bit error probability of 10^-4 along with the allowed data rates:

(a) 5 kHz;
(b) 10 kHz;
(c) 100 kHz;
(d) 1 MHz.
