This helps minimize interference from neighboring frequencies that are not relevant, thus improving signal quality.<\/span><\/li>\n<li><strong><span>Improved signal-to-noise ratio:<\/span><\/strong><span>\u00a0By suppressing noise and interference outside the desired frequency range, the signal-to-noise ratio (SNR) is improved. This makes it easier for the receiver to better detect weak signals in the target frequency band, which increases the effective sensitivity of the system in practice, even if the technical sensitivity of the receiver itself remains unchanged.<\/span><\/li>\n<li><strong><span>Avoid clipping:<\/span><\/strong><span>\u00a0Strong signals outside the target band can clip the receiver and cause distortion.
