Question

Which among the following results in low sensitivity?

a.

Poor collision mitigation mechanism

b.

Poor signal processing

c.

Poor noise figure

d.

Poor linear noise amplifier performance

Posted under Cognitive Radio

Answer: (c).Poor noise figure Explanation:Noise figure quantifies the amount of self-generated noise at the receiver. It lower sensitivity and makes it difficult to find other users of the spectrum. Decreased sensitivity causes a reduction in the amount of power allowed for transmission.
