👉 Trebbleness is a term used in the context of electrical engineering to describe the level of oscillation or resonance that occurs within an electronic circuit. It refers to the frequency at which an oscillator produces a sustained, high-frequency tone when applied to a load with a specific characteristic impedance. In electronics, trebbleness can be measured by measuring the amplitude and phase shift of the signal produced by the oscillator. A low trebbleness indicates that the oscillator is producing a stable and consistent output
