Drive will increase the amplitude of the harmonics, bias, alters the balance between the unique signal and the harmonics, and the low pass filter attenuates the high-frequency vary. Moreover, we now have an output gain rotary and a meter displaying the present standing of the amplitude in dB.

A Saturation function will increase the gain of the harmonics and causes the unique signal’s gain to lower when the drive rotary is raised. An oversampling operation to the right of the saturation function will increase the sampling rate to lower any aliasing which may happen at lower sampling rates.
