A straightforward analog implementation of an audio amplifier uses transistors in linear mode to create an output voltage that is a scaled copy of the input voltage. The forward voltage gain is usually high (at least 40 dB). If the forward gain is part of a feedback loop, the overall ...

I couldn’t find any instructions on how to replace the amplifier with a different one … which is understandable, because it is usually not a preferable way to do it. Most of the time, damaged electronics can be replaced or repaired but that requires quite some skill (and sometimes a dee...
To find your own best times to post, pay attention to your TikTok analytics and when your audience is most likely to be online. Then, schedule your TikTok posts accordingly. 7. Cross-promote your videos Rather than look for some sort of TikTok view trick, consider how a bit of cross-pro...
Indeed, one paradox associated with COR theory is that, in adverse contexts in which resources have been or are about to be damaged, the tasks of identifying potential opportunities and obtaining resource gains become particularly salient—i.e., they gain value (Chen et al., 2015; Hobfoll et...
Power Stage Gain and Phase To prevent switching noise or gain fluctuations due to changes in nonmeasured parameters from causing small signal instability, conventional wisdom recommends that the crossover frequency, fBW, be kept below the lower FS(MIN)/5 = 200 kHz or fRHPZ/3 = 45.3 kHz. ...
and an LC filter with parasitics also has 2 poles and 1 zero. The parasitic poles may force a slope at the loop gain crossover point (the point at which the open-loop plot crosses the axis; where the gain is 0 dB) up to -40 dB/dec or even more. That means the system’s...
If I execute the "margin" function to obtain the Gain Margin "Gm": >> [Gm,Pm,Wcg,Wcp] = margin(sys); It returns the Gain Margin "Gm = 0" (in absolute units) and the phase crossover frequency is "w = 0 rad/s". In dB, the Gain Marg...
For instance in the subject category “mathematics,” we can find disciplines which have very different behaviors from the bibliometric point of view: there are articles in abstract algebra, which usually gain few citations, and articles in applied/computational mathematics which receive many more ...
What limits the value of the superconducting transition temperature (Tc) is a question of great fundamental and practical importance. Various heuristic upper bounds on Tc have been proposed, expressed as fractions of the Fermi temperature, TF, the zero-t
