A potentiometer is used when the user may have to adjust some parameter in the circuit. There are many different things.that may be made adjustable by the designer. As Matt pointed out, one use is to adjust the gain of the op amp stage. WebAn operational amplifier (op amp) is an analog circuit block that takes a differential voltage input and produces a single-ended voltage output. Op amps usually have three terminals: two high-impedance inputs and a low-impedance output port. The inverting input is denoted with a minus (-) sign, and the non-inverting input uses a positive (+) sign. camper van shows uk

WebThe op amp represents high impedance, just as an inductor does. As C 1 charges through R 1, the voltage across R 1 falls, so the op-amp draws current from the input through R L. This continues as the capacitor charges, and eventually the op-amp has an input and output close to virtual ground because the lower end of R 1 is connected to ground.
