A base band digital transmission system that sends ± A-valued rectangular pulses through a channel at a rate of 20,000 bps is to achieve an error probability of 10^-6. If the noise power spectral density is N₀ = 10^-6W/Hz, what is the required value of A? What is a rough estimate of the bandwidth required?
