Jänniteohjattua

Jänniteohjattua is a Finnish term that translates to "voltage-controlled" in English. It describes a device or system where a parameter is regulated or influenced by the level of an electrical voltage. This concept is fundamental in many areas of electronics and engineering.

In analog electronics, jänniteohjattua elements are common. For instance, voltage-controlled oscillators (VCOs) change their output frequency based on an input voltage. Similarly, voltage-controlled amplifiers (VCAs) adjust their gain in response to a control voltage. These components are crucial in synthesizers, audio processing, and communication systems.

The principle of voltage control extends beyond simple analog circuits. In power electronics, voltage regulators use feedback mechanisms to maintain a stable output voltage, effectively controlling the output based on its own voltage level. In control systems, a voltage signal can be used to command actuators, such as motors or valves, to move or adjust to a specific position or flow rate.

The term jänniteohjattua highlights the direct relationship between a voltage signal and the resulting behavior of a system. This control method offers flexibility and precision, allowing for dynamic adjustments and complex operations in a wide range of technological applications. It is a core concept for understanding how electrical signals are used to manipulate and govern physical processes.
