Tunable
In technical optics or acoustics, a component whose frequency behavior (usually as a transmitter or filter ) can be changed by external control or adjustment within a certain frequency scale is called tunable .
An example is a vibrating string whose pitch or natural frequency can be varied by changing its length or the force with which it is pretensioned.
