What is impulse noise in an image?
Impulse noise is a short duration noise.
1 Which type of noise is most difficult to remove from digital signal?
Impulse Noise is the a noncontinuous noise and one of the the most difficult errors to detect because it occurs randomly. Like a lighting strike, the severity of the static across the radio could be so severe that you couldn't hear the music or like a vinyl record with a scratch, the pops and clicks associated with the hitting the scratch making the sound at that exact moment unrecoverable. Typically though, the impulse noise is an analog burst of energy.
What is the Name and briefly describe four types of noise?
1. White noise 2. Impulse noise 3. Echoes 4. Intermodulation
What is the best description of impulse sound?
a lound noise such as a firework display
What does PIR detect?
detect any changes in the environment (noise level, vibration, temperature)
Which type of distortion occurs when a connection cable is inadequately insulated?
Impulse noise
What is the difference white noise and impulse noise?
Thermal noise occurs in all transmission media and all communication equipment, including passive devices. It arises from random electron motion and is characterized by a uniform distribution of energy over the frequency spectrum with a Gaussian distribution of levels. Noise. Impulse noise is noncontinuous, consisting of irregular pulses or noise "spikes" of short duration, broad spectral density, and relatively high amplitude.
What has the author M J Coates written?
M. J. Coates has written: 'Impulse noise and sound exposure meters' -- subject(s): Industrial noise, Measurement, Noise, Sound analyzers
What does shannon capacity have to do with communications?
It has to do with data communication. It is called the Shannon channel capacity theory where double the bandwidth equals double the highest data rate. This is of course theoretically and does not take into account white noise (thermal noise), impulse noise, attenuation distortion or delay distortion.

How are stimulus and response related?
our senses will detect stimulus and send impulse into the integrating centre(brain) to interpret. the brain will produce appropriate response toward the stimulus to the effector. e.g when Telephone ring, the ears will detect the stimulus(sound) and the brain will produce the response to pick up the phone (copy from Yahoo answers)
What is affector neurons?
these have one or more receptors that detect change in either the external or internal environment, information that is detected is transmitted as an electrical impulse to the CNS by the affector neuron.
