What is the advantage of using external compensation for an op amp?
because it helps in noise reduction,bandwidth maximization
Why should network cables and other low-voltage writing not pass close to fluorescent lights?
Fluorescent light emit a small amount of electrical noise, which can be picked up by external wires if they are too close.
Why is FM superior immunity to noise?
FM systems are far better at rejecting noise than AM systems. Noise generally is spread uniformly across the spectrum (the so-called white noise, meaning wide spectrum). The amplitude of the noise varies randomly at these frequencies. The change in amplitude can actually modulate the signal and be picked up in the AM system. As a result, AM systems are very sensitive to random noise. An example might be ignition system noise in your car. Special filters need to be installed to keep the interference out of your car radio. FM systems are inherently immune to random noise. In order for the noise to interfere, it would have to modulate the frequency somehow. But the noise is distributed uniformly in frequency and varies mostly in amplitude. As a result, there is virtually no interference picked up in the FM receiver. FM is sometimes called "static free, " referring to its superior immunity to random noise.
What is noise immunity in digital electronics?
Noise immunity is the ability of a system to perform even when there is noise present. The higher the level of noise a system can still operate under, the higher the noise immunity.
What do engineers use the signal to noise ratio for?
Signal to noise ratio is a measure of signal strength to the background noise. Engineers use the signal to noise ratio to improve digital signal processing.
How can the words ''external noise'' be used in a sentence?
Example: Any external noise that occurred was blocked by the sound-proof headphones.
What noises do the Bose noise cancelling headphones mute out?
Any unwanted noise is muted with the noise cancelling headphones. For example if there is a baby on the plane that is crying. The headphones will mix the noise from your music/media and the external noise and cancels out the external noises.
Is noise an internal stimulus?
It is an external stimulus.
Can you get an external soundcard so that you eliminate the noise inside your computer case?
There are a wide range of external soundcards available.
Are there wireless noise canceling headphones that use white noise and not music?
Noise canceling headphones use neither white noise nor music. True noise canceling headphones use microphones that pick up outside sounds, amplifiers to invert those sounds, and combining circuits to combine the signal to be played with this inverted external sounds before feeding it to the speakers. The external noise vanishes by cancellation, which is why they are called "noise canceling".
Types of Noise in the theory of communication?
The word 'Noise' in communication theory is a barrier to communication that may weaken or destroy a message that is trying to be relayed There are a number of ways to classify noise. It can be subdivided according to type, source, effect, or relation to the receiver, depending on circumstances. In order to make the classification more compact, noise sources can be divided into two main groups: • Noise whose sources are external to the receiver (External Noise) and • Noise source created within the receiver itself (Internal Noise). types include: Shot noise; Johnson noise; Partition noise and White noise
What is the frequency range of active noise suppression of the Bose QuietComfort 2 Noise Cancelling Headphones?
Noise cancellation is more effective at lower frequencies, but reduces most external sound.
What in a automobile engine serves no purpose but without it the engine does not work?
Noise. Without noise, it can't work. Noise is in an engine, and without it does not work. Every engine has to make some kind of noise, internal or external, inside or outside the engine.
What is the advantage of using external compensation for an op amp?
because it helps in noise reduction,bandwidth maximization
What is channel noise in communication system?
Channel noise in communication systems is the crackling or high-pitched noises you get in addition to what you want to hear. It is often caused by external electronic interference.
When we talk on a cell phone and need to keep asking Can you hear me now this barrier to listening is known as what noise?
external
What is physical noise in business communication?
In business communication, physical noise refers to any external stimulus that distracts a person from receiving the intended message sent by a communicator. It negatively affects the business environment.
