(b) The thermal noise power of a channel with a bandwidth of 400kHz is 1.776 x 10¹⁵ watts, what is its operating temperature in C?

(c) Consider a communication channel with 500 kHz bandwidth.

(i) If one wishes to transmit at a data rate of 8.3Mbps, what is the minimum signal-to-noise ratio in dB required to accomplish this?

(ii) If the effective data rate is 80% of the maximum channel data rate.

What is ratio of signal energy per bit to noise power density (i.e. Eb/N0)?
