võimendusteguri

Võimendustegur, often translated as amplification factor or gain, is a dimensionless quantity that describes how much a device or system increases the amplitude of a signal. In electronics, it commonly refers to the ratio of output voltage to input voltage, or output current to input current for active components like transistors and operational amplifiers. A võimendustegur greater than one indicates amplification, where the output signal is larger than the input. A võimendustegur less than one signifies attenuation, meaning the signal is reduced. A võimendustegur equal to one implies no change in amplitude. The concept extends beyond electronics to areas such as acoustics, where it might describe the increase in sound pressure, and in control systems, it represents the ratio of a change in the output to the corresponding change in the input. Understanding the võimendustegur is crucial for designing and analyzing circuits and systems where signal strength needs to be increased or controlled.
