A simple example of white noise is when the Radio does not capture any radio station, we can hear the white noise. In this project, we will build a Simple White Noise Generator Circuit using a single transistor, two resistors, and one Zener diode and Electrolytic Capacitor. Use of White Noise Generator. White noise has a wide range of usage.
Simple White Noise Generator Circuit

Simple White Noise Generator Circuit used to generate white noise in audio signals, which is very helpful in enhancing music. In electronics, the word White Noise resembles the word in physics “White Light” which is a mixture of all other light colors, similarly white noise is a mixture of different frequencies and it also has a constant power spectral density.
LEAP#474 BJT White Noise Generator
https://leap.tardate.com/audio/audioeffects/whitenoisegenerator/
There’s a very common circuit using S9014 transistors as a white noise generator. One transistor produces the noise, and a few amplification and buffer stages are added to provide line and headphone output. It shows up in kits like the EQKit “White Noise Generator”. This is widely available, for example from a seller on aliexpress. Martyn Davies has a very good construction …
A Portable White Noise Generator Circuit - EEWeb

1 day ago · A Portable White Noise Generator Circuit. An adjustable white noise generator is a handy tool that can be used to examine the circuit or a communication line under some random noises to make sure about the stability of the device in real and harsh environments. The current consumption of the device is low, so you can power the circuit using a ...
White Noise and Pink Noise Generator Circuit - …
https://www.homemade-circuits.com/white-noise-and-pink-noise-generator-circuit/
The Q1 zener noise current passes to the Q2 base, causing the generation of around 150 millivolts white noise at the output . This `zener' configuration, no only works like a noise source, but also does the job of biasing Q2 effectively, and the Q2 noise output is applied straight to the White Noise output.

Audio noise generator drives earphones or small speaker - This is a circuit that generates white noise, rolled-off to drive earphones or a small speaker. White noise creates is a "rushing" sound, which sounds something like air rushing by your ear (s).
White Noise Source – Electric Druid
https://electricdruid.net/white-noise-source/
A pure white audio noise generator using an 8 pin PIC 12F675. This pages describes a simple digital noise source that produces pure white noise over the whole audio band – out to more than 40Khz, in fact. With filtering, you can derive pink noise and other colours. The circuit diagram included below was developed from the famous Polyfusion noise generator, and can produce …
Noise Generator Circuit - Making Easy Circuits
https://makingcircuits.com/blog/noise-generator-circuit/
How the Circuit Works. The main component of the circuit is IC1, a relaxation oscillator used. It is provided with positive feedback through P1-R2 and negative feedback by P3-P2-R3-C1. D1, a Zener diode, is the source of the noise. P3 acts as the coarse modulator and P2 as the fine one in the amplification of the noise. P1 is used to set the noise bandwidth, with …
White noise source flat from 1Hz to 100kHz - EDN
https://www.edn.com/white-noise-source-flat-from-1hz-to-100khz/
If this is too much noise for the circuit under test, then the 1kΩ R8 & R9 can be used to advantage in making a voltage divider to lower the noise level to any desired value. Figure 2 shows the resulting noise of the circuit, which is flat from 1Hz to 100kHz. The slight high frequency roll-off at 100kHz in the x100 output is less than 0.5dB and could be accounted for …
