This is convenient because what would require multiplication and division under the ordinary scheme only requires simple addition and subtraction in the dB scheme. For gain, the amplitude is measured ...This is convenient because what would require multiplication and division under the ordinary scheme only requires simple addition and subtraction in the dB scheme. For gain, the amplitude is measured in dB, while the frequency is normally presented in log form. For a phase plot, phase is measured in degrees, and again, the frequency axis is logarithmic. The changes in gain and phase at the frequency extremes are caused by lead and lag networks.
