What does analog radio receiver signal compression do to high frequency received signals?

Signal compression in an analog radio receiver primarily affects how high-frequency signals are processed. When high-frequency signals are received, compression reduces the signal amplitude, which helps to mitigate distortion and allows for a clearer overall reception of the desired audio or data.

By lowering the amplitude of high-frequency signals, the receiver can prevent overload and maintain fidelity, particularly in situations where multiple signals may interfere with each other. This process is important in maintaining a balanced sound or data output, as it ensures that no single frequency range dominates the output, which could lead to a muddy or unclear signal.

In this context, while amplifying the signal and enhancing clarity are desirable outcomes of processing, the specific action of reducing the signal amplitude is the direct effect of signal compression on high frequencies. This definition aligns well with the operational principles of analog radio receivers.
