Determine the thermal noise power density [No] in decibels, given the following information: T=295oK, signal bandwidth of 4kHz. a. -167.88 dB b. +203.9 dB c. -203.9 dB d. -137.88 dB

Select the correct statement(s) regarding signal-to-noise ratio (SNR) calculations. a. When determining the non-decibel value of S/N, mixing units (i.e., mW and W) between S and N is permissible (e.g., S(mW)/N(W)) b. SNR can only be given in decibel form because it represents a ratio of powers c. The decibel value of SNR is given by: [SNR]=[S]-[N], where "[ ]" indicates decibel values d. The decibel value of SNR is given by: [SNR]=[S]/[N], where "[ ]" indicates decibel values

Determine the SNR in decibels given a receive signal of 10E-6 watts, and [N]=-128 dBW. a. 128dB b. 48.41 dB c. 78 dB d. -98.41dB

Select the way(s) in which the data rate capacity of a link can be increased.

		a. Increase the number of levels (M) allowed per symbol
		b. Increase signal frequency
		c. Increase frequency bandwidth
		d. All of the above
