2) (15pts) In a PAM baseband digital communication system, an M-ary system has a
channel bandwidth of 2 KHz. The channel introduces 10dB of losses and AWGN noise
with a power spectral density of 1*10-6 W/Hz. The application requires a bit rate of 4.8
Kbps and BER of less than 10^-6. Estimate the require transmit power.
