lähtöimpedanssia
Lähtöimpedanssi, or output impedance in English, is a fundamental concept in electrical engineering that describes the opposition to alternating current flow within a source device, such as an amplifier or a signal generator. It is represented by the symbol Zout and is measured in ohms. This impedance is a complex quantity, meaning it has both a resistive and a reactive component, though in some simplified analyses, only the resistive part might be considered.
The output impedance is a characteristic of the internal circuitry of the source. When a load is
