Question

Superconducting analog filters can reduce noise and interference introduced by wide bandwidth of SDR architecture.

(a) True

(b) False

The question was posed to me during an internship interview.

My query is from RF and IF Processing Tradeoffs in division Technology Tradeoffs in Software Defined Radio of Cognitive Radio

Answer 1

Right answer is (a) True

The best I can explain: Superconducting analog filters can reduce noise and interference introduced by wide bandwidth of SDR architecture. The combined use of superconducting filter and regular anti-aliasing filter can offer better spectral purity.
