kontrollspenning

Kontrollspenning, a Norwegian term, translates to "control voltage" in English. It refers to a type of electrical signal that is used to regulate or adjust the behavior of another electrical component or system. Unlike a power supply voltage that delivers energy to operate a device, control voltage is a signal that conveys information about how the device should operate. This information can dictate parameters such as frequency, amplitude, gain, or other operational characteristics.

The application of control voltage is widespread in electronics, particularly in analog and modular synthesizer systems. Here, it is used to modulate various sound parameters like pitch, filter cutoff frequency, or amplifier volume in real-time. For instance, a keyboard might send out a control voltage signal proportional to the key pressed, which then controls the pitch of an oscillator. Similarly, an envelope generator can produce a control voltage that changes over time, shaping the attack, decay, sustain, and release of a sound.

Beyond synthesizers, control voltage finds use in industrial automation, test and measurement equipment, and various other electronic circuits where a variable electrical signal is needed to manage or influence a process. The key characteristic of a control voltage is its informational role, guiding the operation of a system rather than directly powering it.
