Most filters are based on an RC circuit – resistor plus capacitor – with their combination yielding the cutoff frequency of the filter. In most designs, the resistor or “R” is varied to change that frequency – either by a front panel knob, or a control voltage converted into either a variable resistance or a variable current (according go Ohm’s Law, a voltage across a resistor equals current).
