Why is it good to match receiver bandwidth to the bandwidth of the operating mode?
It is required by FCC rules
It minimizes power consumption in the receiver
It improves impedance matching of the antenna
It results in the best signal-to-noise ratio✓Ճիշտ պատասխան
Բացատրություն
Noise power admitted by a receiver is proportional to its bandwidth, so a filter wider than the signal adds noise without adding signal, while a narrower one discards signal energy. Matching the two maximizes the signal-to-noise ratio.
