This classic tone control circuit uses a low noise transistor model which is interesting. The transistor makes the adjustment more suitable for the person to hear. The variable resistor also plays an ...

Theory of Operation This block utilizes the baxandall-tone circuit, which has a different gain for the bass and treble components. We need to ensure that, with a 100k$\Omega$ voltage source, the gain ...

Nevertheless, a single-adjustment tone control often can be useful for fine balance adjustment or where multiple controls are impractical or unnecessary. A simple version of such a control ...

A monolithic IC which contains dual-channel volume control circuits, tone control circuits, and function switches is discussed. The IC has excellent characteristics, such as total harmonic distortion ...
