Question

Which among the following is the impact of having poor spur free dynamic range?

a.

Difficulty in short signal detection

b.

Overloading

c.

Additive noise

d.

High complexity

Posted under Cognitive Radio

Answer: (c).Additive noise Explanation:Spur free dynamic range is the maximum range over which self-generated signals are absent. Poor SFDR results in spur which resembles tonal signals and give the appearance of an occupied signal. This results in the addition of noise to the received signals.
