Seek animal foods as your primary source of choline, but augment with plant based sources as desired. Cruciferous Veggies Veggies from this group, including cauliflower, cabbage, bok choy and broccoli, boast around 65 mg of choline per cup cooked.
Since its normally easier to conduct measurements of voltage rather than power, some prefer using the voltage of a system as a reference. As a result, the dBu unit of measure is used many times in audio systems vice dBm. The dBu unit is calculated by: A = 20log(V2/V1).In this formula, the reference level is 0.77 volts rms. In most audio equipment, the normal dBu line level is 4 dBu.ince its normally easier to conduct measurements of voltage rather than power, some prefer using the voltage of a system as a reference.

The use of dBm and dBv has been deprecated and replaced by the dBu unit which is measured regardless of impedance. When +4dBu or -10dBV values are reconciled to the other's scale and the actual difference in voltage is compared you can see that there is a 11.79dB difference in voltage levels.he unit names dBu, dBv, dBV, and dBm all have case sensitive spellings and have specific defintions regarding audio signal levels. Professional analog gear is measured with dBu and dBv and dBm unit scales.
