only on random valued impulse noise and [33] is compu-tationally expensive. 6. d) Impulse noise. Continuous noise is exactly what it says on the tin: it’s noise that is produced continuously, for example, by machinery that keeps running without interruption. Here’s a breakdown of the different types of noise that affect us all. Impulse noise Impulse noise is generally only a minor annoyance for analog data. FEC coding, interleaver depth, and framing parameters are selected to maximize the impulse noise protection while not causing an excessive increase in transmit power or equivalently, loss of net coding gain. Impulse noise is one the type of noise which modifies the pixel values randomly. 2. With the rapid development of computer science and technology in modern society, image science is widely used in various fields, especially in medicine fie converters, fluorescent lamps, TV sets and computer monitors [4]. Impulse noise is irregular pulses or spikes( a signal with high energy in a very short period) generated by phenomena like that comes from power lines, lightning, spark due to loose contact in electric circuits and so on. For example, voice transmission may be corrupted by short clicks and crackles with no loss of intelligibility. The experimental results show that the method is superior to other methods in terms of effectiveness impulse noise (salt and pepper noise) for medical images (CT or MRI). The successful use of fuzzy set theory performance on many domains, together with the increasing requirement for processing In [34], a neural network was trained for impulse detection. These settings are not interchangeable; the true peak value is the maximum value of the noise waveform, while the impulse measurement is … Characteristic of Impulse Noise. Many sound level meters also have "peak" and "impulse" response settings for measuring transient sounds (sounds that decay or pass with time). 1. International Journal of Computer Applications (0975 – 8887) Volume 21– No.3, May 2011 32 Sun et al., [2] provided an impulse noise image filter using fuzzy sets. In [20], which is a fuzzy technique, the membership func-tion is very crucial for the performance of the noise detec- The Four types of noise. A relatively constant type of noise, much like the static you hear when a radio is tuned between two stations. In a digital subscriber line (DSL) network, a net coding gain penalty is determined for provision of impulse noise protection. It is a primary source of bit-errors in digital data communication that kind of noise introduces burst errors. However, impulse noise is the primary 8. The impulse noise occurs very often in the network power and it is characterized by … Impulse noise is a primary source of bit-errors in digital data communication. d.Impulse noise: Impulse noise is irregular pulses or noise spikes of short duration generated by phenomena like lightning, spark due to loose contact in electric circuits, etc. This kind of noise introduces burst errors. But it works only on fixed impulse noise and the learning method of the network is supervised. Impulse noise, which is a type of electromagnetic interference (EMI) typically emanating from power transmission, radio, TV, electronics, and cell phones, has become more prevalent with the rise of the latest high-speed DSL technologies (including VDSL2). This type of noise can be cl assified into two categories such as static and dynamic (random). Typically, crosstalk is of the same order of magnitude (or less) as thermal noise. C. Impulse Noise The major sources of impulse noise are switching power supplies, thyristor regulators or collector motors. Impulse Noise A non constant noise that is one of the most difficult errors to detect because it can occur randomly. Continuous noise. Impulse noise is sporadic, non-contiguous, consisting of irregular pulses or noise spikes of short duration and of relatively high amplitude as high as several hundred micro-volts and may occur in bursts or discrete impulses, as shown in Figure 2.
