## JokeA Most jokes contain two components: joke setup (for example, "A man walks into a bar...") and a punchline, which, when juxtaposed with the setup, provides the necessary irony to elicit laughter from the audience. ## Psychology of jokesWhy we laugh has been the subject of serious academic study, examples being: - Sigmund Freud's
*"Jokes and Their Relationship to the Unconscious"*. - Marvin Minsky in
*Society of Mind*.
- Edward de Bono in
*"The mechanism of the mind"*and*"I am right, you are wrong"*.
Laughter, the intended human reaction to jokes, is healthful in moderation, uses the stomach muscles, and releases endorphins, natural happiness-inducing chemicals, into the bloodstream. One of the most complete and informative books on different types of jokes and how to tell them is ## Types of jokesJokes often depend for humour on the unexpected, the mildly taboo (which can include the distasteful or socially improper), or the playing on stereotypes and other cultural myths. Many jokes fit into more than one category. ## Mathematical jokes
There are numerous jokes related to mathematics. Many of them are in-jokes, but may also be understandable by laymen. A series of them parodies mathematical/logical chains of reason. - Mathematical proof:
- Logic
Jokes in a certain category superficially look like math, but their essence is more akin to chemical composition. ## Yo' mama jokes
- Yo mama's so dumb when your dad said it's chilly outside, she ran out with a spoon.
- Yo mama so dark that she can leave fingerprints on charcoal.
- Yo mama so fat when she gets on the scale it says to be continued.
- Yo mama so fat, when her pager goes off, people think she's backing up.
- Yo mama's glasses are so thick, she can see the future.

The following joke circulates for quite some time, with many different versions for <President> and <Other Country>. Note that this power spectral density corresponds to a delta function for the covariance function of There are two large categories of this type of jokes. We choose the minimum phase filter so that the resulting inverse filter is stable. Jokes in a certain category superficially look like math, but their essence is more akin to chemical composition. Suppose we have a wide-sense stationary, continuous-time random process defined with the same mean μ, covariance function
Laughter, the intended human reaction to jokes, is healthful in moderation, uses the stomach muscles, and releases endorphins, natural happiness-inducing chemicals, into the bloodstream. We can simulate this signal using frequency domain techniques. Why we laugh has been the subject of serious academic study, examples being:. and power spectral density. . We can simulate any wide-sense stationary, continuous-time random process with constant mean μ and covariance function. Most jokes contain two components: joke setup (for example, "A man walks into a bar...") and a punchline, which, when juxtaposed with the setup, provides the necessary irony to elicit laughter from the audience. For whitening, we feed any arbitrary random signal into a specially chosen filter so that the output of the filter is a white noise signal. putting a custard pie in somebody's face). We choose the filter so that the output signal simulates the 1st and 2nd moments of any arbitrary random process. A practical joke differs in that the humour is not verbal, but mainly visual (e.g. For simulating, we create a filter into which we feed a white noise signal. A Yo mama so fat, when her pager goes off, people think she's backing up. By diagonalizing Logic "The mechanism of the mind" and "I am right, you are wrong". where. Marvin Minsky in Society of Mind. We can simulate the 1st and 2nd moment properties of this random vector with mean and covariance matrix K_{xx} via the following transformation of a white vector :.
Sigmund Freud's These two ideas are crucial in applications such as channel estimation and channel equalization in communications and audio. To Two theoretical applications using a white random vector are the I.e., it is a zero mean process for all time and has infinite power at zero time shift since its autocorrelation function is the Dirac delta function. A continuous time random process A random vector is a white random vector if and only if its mean vector and autocorrelation matrix are the following:. White noise machines are sold as privacy enhancers and sleep aids. White noise can be used to disorient individuals prior to interrogation and may be used as part of sensory deprivation techniques. White noise is used as the basis of some random number generators. He or she can then adjust the overall EQ to ensure a balanced mix. To set up the EQ for a concert or other performance in a venue, a short burst of pink noise is sent through the PA system and monitored from various points in the venue so that the engineer can tell if the acoustics of the building naturally boost or cut any frequencies. It is also used to generate impulse responses. It is used extensively in audio synthesis, typically to recreate percussive instruments such as cymbals which have high noise content in their frequency domain. White noise has also been used in electronic music, where it is used either directly or as an input for a filter to create other types of noise signal. urban traffic noise). White noise is used by some sirens for emergency vehicles, due to its ability to cut through background noise (e.g. Here in order to submerge distracting, undesirable noises (for example conversations, etc.,) in interior spaces, a constant low level of noise is generated and provided as a background sound. One use for white noise is in the field of architectural acoustics. There are also other "colors" of noise, the most commonly used being pink and brown. White noise is the generalized mean-square derivative of the Wiener process or Brownian motion. Gaussian white noise has the useful statistical property that its values are independent (see Statistical independence). These models are used so frequently that the term additive white Gaussian noise has a standard abbreviation: AWGN. Gaussian white noise is a good approximation of many real-world situations and generates mathematically tractable models. Thus, the two words "Gaussian" and "white" are often both specified in mathematical models of systems. However, neither property implies the other. It is often incorrectly assumed that Gaussian noise (see normal distribution) is necessarily white noise. Noise having a continuous distribution, such as a normal distribution, can of course be white. For example, a binary signal which can only take on the values 1 or 0 will be white if the sequence of zeros and ones is statistically uncorrelated. Any distribution of values is possible (although it must have zero DC component). Being uncorrelated in time does not however restrict the values a signal can take. The image to the right displays a finite length, discrete time realization of a white noise process generated from a computer. the distribution of a signal across all angles in the night sky). The signal is then "white" in the spatial frequency domain (this is equally true for signals in the angular frequency domain, e.g. The term white noise is also commonly applied to a noise signal in the spatial domain which has zero autocorrelation with itself over the relevant space dimensions. . In practice, a signal can be "white" with a flat spectrum over a defined frequency band. By having power at all frequencies, the total power of such a signal is infinite. An infinite-bandwidth white noise signal is purely a theoretical construct. In other words, the signal's power spectral density has equal power in any band, at any centre frequency, having a given bandwidth. |
