What effect does analog radio receiver signal compression have on high frequency signals?

Signal compression in an analog radio receiver is a process that modifies the dynamic range of a signal. When it comes to high frequency signals, signal compression effectively reduces their amplitude. This is primarily because high frequency signals are often more susceptible to various forms of distortion and interference.

During compression, the receiver manipulates the amplitude of the incoming signal to maintain a more consistent output level. This can manifest as a reduction in the amplitude of high frequency components, which may be less robust and therefore more easily affected by signal degradation.

By reducing the high frequency signal amplitude, the receiver aims to create a more balanced output that can prevent distortion and maintain overall signal integrity. This dynamic adjustment helps ensure that the high-frequency parts are not overwhelming the system, which could lead to clipping or other unwanted artifacts in the audio spectrum.

The other choices do not accurately describe this process in relation to high frequency signals, which solidifies the understanding that the correct influence of compression is indeed a reduction in their amplitude.
