White Noise Generator With the 741 (CB401)

This circuit uses a transistor as noise source and a 741 IC as amplifier, sourcing a high intensity signal to the output. The circuit needs a dual supply and other operational amplifiers can be used. The noise level is adjusted by the 100 k ohm potentiometer.
