What is Understanding 3dB Bandwidth Definition about?
Bandwidth is defined as the range of frequencies over which a system operates or passes signals satisfactorily. It is typically measured as the frequency difference between the upper and lower -3dB cut-off frequencies. The -3dB point refers to the frequency where the power of the signal is half its maximum value. Bandwidth is expressed in decibels rather than a percentage because decibels provide a logarithmic scale that matches how we perceive changes in power. Specifically, the -3dB point corresponds
