Discuss the concept of Karhussen Locve expansion?

User Avatar

Asked by Wiki User

Concept of Karhunen-Loève expansion :

Karhunen-Loève theorem : In the theory of stochastic processes, the Karhunen-Loève theorem (named after Kari Karhunen and Michel Loève) is a representation of a stochastic process as an infinite linear combination of orthogonal functions, analogous to a Fourier series representation of a function on a bounded interval. In contrast to a Fourier series where the coefficients are real numbers and the expansion basis consists of sinusoidal functions (that is, sine and cosine functions), the coefficients in the Karhunen-Loève theorem are random variables and the expansion basis depends on the process. In fact, the orthogonal basis functions used in this representation are determined by the covariance function of the process. If we regard a stochastic process as a random function F, that is, one in which the random value is a function on an interval [a, b], then this theorem can be considered as a random orthonormal expansion of F.

In the case of a centered stochastic process {Xt}t [a, b] (where centered means that the expectations E(Xt) are defined and equal to 0 for all t) satisfying a technical continuity condition, admits a decomposition

Xt =∞∑k=1Zkek(t).

where Zk are pairwise uncorrelated random variables and the functions ek are continuous real-valued functions on [a, b] which are pairwise orthogonal in L2[a, b]. The general case of a process which is not centered can be represented by expanding the expectation function (which is a non-random function) in the basis ek .
Moreover, if the process is Gaussian, then the random variables Zk are Gaussian and stochastically independent. This result generalizes the Karhunen-Loève transform. An important example of a centered real stochastic process on [0,1] is the Wiener process and the Karhunen-Loève theorem can be used to provide a canonical orthogonal representation for it. In this case the expansion consists of sinusoidal functions.

The above expansion into uncorrelated random variables is also known as the Karhunen-Loève expansion or Karhunen-Loève decomposition. The empirical version (i.e., with the coefficients computed from a sample) is known as Proper orthogonal decomposition or Principal component analysis.

What is dither in digital image processing?

User Avatar

Asked by Wiki User

Dither is a technique used in digital image processing to reduce banding or other visual artifacts by adding noise to the image. This noise helps smooth out transitions between colors, resulting in a more natural and pleasing appearance. Dithering is commonly used in situations where the color depth is limited, such as with web graphics or computer displays.

What is the difference between audio mixing and mastering?

User Avatar

Asked by Wiki User

There are various technical aspects involved in producing premium-quality audio content. For making a clear, perfect pitch and pleasing audio content, two major factors are mixing and mastering. The first step of creating a song is mixing, where experts work on balancing, treating, and combining multiple tracks of music. In this process, experts also add various individual sounds together to make a melody.

On the other hand, mastering is the final process of audio production, where experts give the final touch to content before going out for distribution. The mastering process involves various works, such as making the track louder and making the track sound better. People require skills like attention to detail and years of experience for this work.

Convert ac voltage rms to dc voltage?

User Avatar

Asked by Wiki User

The dc voltage of a rectified ac voltage will be the peak value of the ac voltage less the forward voltage drop of the diode.

The rms voltage of a sinusoidal ac voltage is sqrt(peak) / 2, but you also have to consider if the ac voltage is balanced around zero.

For a normal US house voltage of 117VAC, the peak voltage is about 165V, or 330V peak to peak. Your dc voltage is then around 164V.

Run that rectified voltage through a capacitor, and you will still have 164V peak value, but the voltage over time will dip because the capacitor will discharge during diode off time, and recharge when it turns back on.

Answer

A given value of a.c. rms voltage is exactly equivalent to the corresponding value of d.c. voltage. For example, 120 V (rms) is exactly equivalent to 120 V d.c. This is why the alternative name for 'rms voltage' is 'effective voltage'. This is based on the fact that a current of, say, 10 A (rms) will do exactly the same amount of work as a d.c. current of 10 A. And, of course, voltage and current are proportional.

What is the zener region?

User Avatar

Asked by Wiki User

The zener region describes the area on the performance curve (a graph of voltage across versus current through the junction) of a zener diode. The diode acts like a "regular" diode in the forward biased direction. When some 0.7 volts or so is reached, forward current begins to climb rapidly as voltage is increased (for silicon diodes.) But in the reverse direction recall that as the diode is reverse biased, a small amount of current will flow (because of minority carriers). This "trickle" of current will continue until the "zener voltage" is reached, and then the diode will begin to conduct heavily. On the graph, this is the zener region. Zener diodes can be made to breakdown at a specific voltage, and their ability to conduct reverse current can be increased by manufacturing a larger diode. That means there are a range of voltages and wattages of zener diodes available. Wikipedia has more information and that graph. Use the link provided to get there.

What is the difference between electronics and communication and electronics and telecommunication engineering?

User Avatar

Asked by Wiki User

The term engineering means "to design something to resolve a problem" (no matter the type of problem). Electronics and Telecommunication engineering could very well mean "the design of components to further the advancement of technology" while electronics and communication would mean "the study of current technology and how to use it" Electronics communication is the art of transferring DATA from one device to another such as computer networks operating on a hub in some office. Telecommunication is the art of using telephones lines or other media to transfer DATA. Both require different design criteria even thought very similar in nature. Engineering is a word to describe the process of designing one art or the other.

Operation of an inverter?

User Avatar

Asked by Wiki User

An inverter generally changes DC to AC

DC current is rapidly switched in polarity across a transformer by hi current solid state switches. The secondary of the transformer steps up the voltage and this output is conditioned to remove excess noise. The output is more like a squarewave than a sinewave, but acceptable to many lo tech devices. There are many details, but this is the basic inverter. More $$$ and you get cleaner AC, and even sine waves.

Discussion about amplitude demodulator?

User Avatar

Asked by Mmasud

A modulator modulates the carrier frequency, while a demodulator detects the modulation on the carrier wave and recovers the original lower frequency waveform at the destination. For many years the modulated carrier wave was converted to a radio signal. Now it is often an electrical signal which is sent down a teleohone line; the information is usually a set of pulses going between computers. When computers are connected to each other in a two-way conversation, the MOdulator and DEModulator are combined into a single device called a MODEM.
