El escenario
Design an op-amp based soft clipper for audio signals with adjustable clipping threshold.
Qué hay en este dibujo
Lee las decisiones que hay detrás.
01
Use a potentiometer to adjust the clipping threshold by dividing the input signal.
02
Implement soft clipping with back-to-back diodes in the feedback loop of an op-amp for symmetrical distortion.
03
Set the gain with Rf and R3 to control the non-clipping amplification.
When a soft distortion effect is desired for musical instruments or audio signals, especially when the user wants to control the amount of distortion.
