In electronics, gain is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of a signal from the input to the output port by adding energy converted from some power supply to the signal. It is usually defined as the mean ratio of the signal amplitude or power at the output port to the amplitude or power at the input port. It is often expressed using the logarithmic decibel (dB) units ("dB gain"). A gain greater than one (greater than zero dB), that is amplification, is the defining property of an active component or circuit, while a passive circuit will have a gain of less than one.The term gain alone is ambiguous, and can refer to the ratio of output to input voltage (voltage gain), current (current gain) or electric power (power gain). In the field of audio and general purpose amplifiers, especially operational amplifiers, the term usually refers to voltage gain, but in radio frequency amplifiers it usually refers to power gain. Furthermore, the term gain is also applied in systems such as sensors where the input and output have different units; in such cases the gain units must be specified, as in "5 microvolts per photon" for the responsivity of a photosensor. The "gain" of a bipolar transistor normally refers to forward current transfer ratio, either hFE ("beta", the static ratio of Ic divided by Ib at some operating point), or sometimes hfe (the small-signal current gain, the slope of the graph of Ic against Ib at a point).
The gain of an electronic device or circuit generally varies with the frequency of the applied signal. Unless otherwise stated, the term refers to the gain for frequencies in the passband, the intended operating frequency range of the equipment.
The term gain has a different meaning in antenna design; antenna gain is the ratio of radiation intensity from a directional antenna to

(mean radiation intensity from a lossless antenna).

Hello! Any recommendations for multivitamins na possible din po ako maggain ng weight? Payat po ako ever since, di lumalagpas ng 40kg. May time pa na bumagsak sa 35kg weight ko nung nagaaral ako dahil kulang sa tulog at hassle ng pagcommute (lrt+mrt puro hagdan huhu). Now working ako for night...
Hello ka phc, long time lurker nako dito since 2015 hahaha. Ask ko lang paano maging Elite? kase ang tagal ko na dito di ko pa na eexplore yung ganyan.
Always maintain estab lang ako like mag post ng isang topic then reply sa limang topic.
Pa help po or palink nung rules, thank you :)
Sikat ito sa tiktok ngayon e effective kaya itong pampataba? Or may suggestion kayo iba , currently, 27 yrs old nako, 5”8 height around 45-50 kgs lang ako e
ano po daily routine nyo para pumayat or as is lang yung weight? so far nag gain talaga ako ng weight simula nung pandemic hai .. may tips po ba kayo dyan
sino dito yung gustong tumaba ? syempre pag hindi na talaga kaya ng mano manong kain kaylangan mo ng appetite booster .
May alam akong product ( wala po akong balak mag advertise , nagsheshare lang po ako wag sanang madelete tong thread ) yung pangalan po ng product is ling zhi , di ko po alam...
Good Day, ano bang mabisang weight gain supplements na alam nyo?
2 months akong nag workout sa gym, at nag ka muscle gain ako at dumagdag ng 8kg ang bigat ko at masasabi ko naman effective talaga dahil nagbago appetite ko pero ngayong darating na pasukan na ay mahihirapan nanaman ako mag...
