... frequency and damping. There are many measures of describing damping. This paper prefers the damping ratio Q = 1/(2ξ ) and the quality factor Q, which is approximately equal to a resonance gain of the lightly damped systems. For a normalized value of the quality factor Q the substructure natural fre ...

How to Find Ground Loops and Prevent AC Hum
... When you hear hum in an audio system, it's almost always caused by a loop antenna effect between two or more pieces of gear, across signal lines. A loop antenna is formed by having a loop of wire where the beginning and end of the loop are connected - the loop can be any shape. The loop antenna(e) i ...

TDA8921TH class-D audio amplifier 2 x 50W single chip
... During the start-up sequence, when the mode pin is switched from standby to mute, the condition at the output terminals of the power stage are checked. In case of a short of one of the output terminals to VDD or VSS the start-up procedure is interrupted and the systems waits for un-shorted outputs. ...
