The relationship between dB (decibel) and multiplier
dB is a unit for expressing relative power or level, and the calculation formula is shown in ① of Table 1. dBm is a unit for expressing absolute power, and the calculation formula is shown in ② of Table 1. dbμ is a unit for expressing absolute level, and the calculation formula is shown in ③ of Table 1. Table 2 shows the corresponding relationship between dB value and magnification of voltage and current.
