From subelement E4 - E4C
E4C11
Answer: DWhy does input attenuation reduce receiver overload on the lower frequency HF bands with little or no impact on signal-to-noise ratio?
AThe attenuator has a low-pass filter to increase the strength of lower frequency signals
BThe attenuator has a noise filter to suppress interference
CSignals are attenuated separately from the noise
DAtmospheric noise is generally greater than internally generated noise even after attenuation
