Posted under Cognitive Radio

Answer: (b).False Explanation:The SNR and DNR can be determined by matching the radio noise floor to the ADC input noise level. This imposes the design rule that the total noise power should be less than half of the least significant bit of ADC. The ratio of spectral density outside the notch filter to the maximum spectral density inside the notch filter gives the Noise Power Ratio.
