võimenduskoefitsienti

Võimenduskoefitsient, often translated as amplification factor or gain, is a dimensionless quantity that describes the ratio of the output signal of an electronic device or system to its input signal. It quantifies how much the signal is increased or decreased in amplitude. A võimenduskoefitsient greater than one indicates that the output signal is larger than the input, meaning amplification has occurred. Conversely, a value less than one signifies signal attenuation, where the output is smaller than the input. A võimenduskoefitsient of one means the output and input signals are equal in amplitude.

In the context of amplifiers, the võimenduskoefitsient is a crucial parameter determining the device's performance. It can be expressed in various ways, most commonly as a simple ratio of voltages, currents, or powers. When expressed as a ratio of powers, it is often converted to decibels (dB) for easier handling of large ranges. The term is also applicable in other fields, such as acoustics, where it describes the increase in sound pressure level, and in optical systems, referring to the amplification of light. Understanding the võimenduskoefitsient is fundamental to analyzing and designing systems that involve signal manipulation.
