Noise (electronic Engineering)

In summary, the conversation discusses the effects of noise on electronic systems and the difficulty in measuring and characterizing it. The choices of frequency and wavelength can also impact the design of an electronic system and its components. Decibels are used to analyze the overall gain and loss of a system. The importance of addressing noise in electronic systems is emphasized.

Noise is basically disturbance created by sorroundings on any particular systems.For example if u have any signal for RF transfer but if there is noise the signal will get distorted which,of course you don't want.
It is difficult to measure bcoz it is result of sorrounding intfrence which cannot be quantified.Sometimes more interaction but sometimes very less.
 

1. What is noise in electronic engineering?

Noise in electronic engineering refers to any unwanted or random disturbance in an electrical signal. It can be caused by various sources such as external interference, thermal fluctuations, or imperfections in electronic components.

2. How does noise affect electronic devices?

Noise can cause a variety of issues in electronic devices, such as reducing the signal-to-noise ratio, distorting the signal, or causing errors in data transmission. In extreme cases, it can even damage the device or cause it to malfunction.

3. How is noise measured in electronic engineering?

Noise is typically measured in decibels (dB) or a similar unit, such as decibels relative to milliwatt (dBm). Different types of noise, such as thermal noise or shot noise, may require different measurement techniques or equipment.

4. How can noise be reduced in electronic circuits?

There are several methods for reducing noise in electronic circuits, such as shielding the circuit from external interference, using low-noise components, and implementing filtering techniques. Designers may also use techniques such as oversampling or dithering to reduce the effects of noise in analog-to-digital conversion.

5. Is all noise considered bad in electronic engineering?

Not necessarily. In some cases, noise can actually be beneficial, such as in random number generation or spread spectrum communication systems. However, in most cases, engineers aim to minimize noise in electronic circuits to ensure reliable and accurate operation.
