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.

CSU/DSUs are made as separate products or are sometimes part of a T-1 WAN card. A CSU/DSU's Data Terminal Equipment interface is usually compatible with the V.xx and RS-232C or similar serial interface.Manufacturers of separate unit or integrated CSU/DSUs include Adtran, Cisco, and Memotec.he Data Service Unit (DSU) manages line control, and converts input and output between RS-232C, RS-449, or V.xx frames from the LAN and the time-division multiplexed (TDM) DSX frames on the T-1 line. The DSU manages timing errors and signal regeneration.
