An Improved Hybrid DSTATCOM Topology to Compensate Reactive
... compensated and the dc-link voltage However, a higher dc-link voltage increases the rating of the VSI, makes the VSI heavy, and results in higher voltage rating of insulated gate bipolar transistor (IGBT) switches. It leads to the increase in the cost, size, weight, and power rating of the VSI. In a ...

Decibel notes
... The gain of an amplifier can also be expressed as a ratio of Voltage Out divided by Voltage In. Since there is a direct relationship between Watts (Power) and Voltage (or Current), the voltage (or current) gain can also be expressed in dB. dB Gain = 20 Log (Voltage Out / Voltage In) Note: The above ...

Ringing artifacts
In signal processing, particularly digital image processing, ringing artifacts are artifacts that appear as spurious signals near sharp transitions in a signal. Visually, they appear as bands or ""ghosts"" near edges; audibly, they appear as ""echos"" near transients, particularly sounds from percussion instruments; most noticeable are the pre-echos. The term ""ringing"" is because the output signal oscillates at a fading rate around a sharp transition in the input, similar to a bell after being struck. As with other artifacts, their minimization is a criterion in filter design.
