Yes, a reverse-biased diode junction can generate shot noise, albeit typically to a lesser extent than in forward bias. Shot noise arises from the discrete nature of charge carriers, and in a reverse-biased condition, the noise is mainly due to the leakage current across the junction. This leakage current results from thermally generated minority carriers, leading to fluctuations in the current that manifest as shot noise. However, the magnitude of this noise is generally much lower than that observed in forward-biased operation.

What does avalanche sound like?
An avalanche sound like a roaring trucktor i think. It sould be like a hurricane.
Why high noise in bipolar junction transistor?
In the case of Bipolar Junction Transistor current conduction is due to both holes and electrons. That's why noise is high in Bipolar Junction Transistor
What is the effect of temperature on photodiode?
photodiodes are basically reverse biased diodes with optical windows that allow like to shine on the PN junction. Like any diode, the leakage current (otherwise known as a photodiodes 'dark' current) increases exponentually with temperature in accordance to William Shockley's idea diode eqation. The other effect in a photo diode is the probability of a photon of a certain energy allowing an electron to cross the PN junction. This is known as the quantum efficiency of the photodiode. Because increasing temperatures increase the vibration of the silicon atoms, making them easier to be knocked loose by a photon. Thus the quantum efficiency of a photodiode will increase with tempature, as well as the thermally induced noise. photodiodes are basically reverse biased diodes with optical windows that allow like to shine on the PN junction.

What are the parameters of the DR25 germanium diode?
The DR25 germanium diode typically features a maximum reverse voltage of around 40V and a forward current rating of about 50mA. Its forward voltage drop is approximately 0.3V to 0.4V at the rated current. The diode is known for its low noise characteristics and is often used in low-frequency applications, such as radio receivers and detectors. Additionally, it has a junction capacitance of about 2pF, making it suitable for high-frequency applications as well.
Does diode make noise?
There are diode tubes that can make noise, but they have not been popular for a number of decades. The solid-state diodes that you find on printed-circuit boards have no moving parts, so are silent, unless they have been damaged in some way.
What form of noise interference is problematic in cable modem uploads?
Noise that household appliances generate
What will be the result if silicon diode is replaced by the germinium diode?
The built is voltage would be lower than silicon diode,more leakage or reverse saturation current,poor thermal stability,high noise and greater conduction in comparison to silicon diodes.
What generates more noise ac motor or dc motor?
dc motors generate more noise.

Correlated and uncorrelated noise?
If I have two source of noise let as say two laser diodes so the pink noise that generate fro both of them is it correlated or uncorrelated
Can the alternator be the problem for the audio?
yes the alternator can generate noise or whine in the speakers.
Why is Avalanche photo diode used when compared to PIN diode?
The output current of a PIN diode is proportional to the light incident . Whereas in APD due to internal multiplication (Avalanche multiplication) of primary photocurrent, higher gains are possible. A small signal current output from the pin diode are to be amplified before applying to next associated receiver circuit. This includes thermal noise in the main signal, giving lower, receiver sensitivity. In case of APD, photocurrent is multiplied before encountering the thermal noise amplifier, giving increased receiver sensitivity.
