### Sampling time sampling frequency calculation of ADC sampling period

ADC conversion is the input analog signal volume, the microcontroller converted to digital volume. Reading the number must wait for the conversion to complete, the completion of a channel reading is called the sampling period. Sampling period generally = conversion time + read time. The conversion time = sampling time + 12.5 clock cycles. The

### Reservoir sampling reservoir sampling algorithm, classical sampling

Random reading of the data, how to ensure that the true random is not possible, because the computer's random function is pseudo-random.But how to ensure the random sampling of the data without considering the random function of the computer?1. Shuffle functions provided by the systemThe C++/java provides a shuffle function that can disrupt the data inside the container and keep it randomly sorted.C++:1 template classclass urng>2 void Shuffle ( Rand

### Common sense concepts such as sound, audio sampling rate, and Sampling Accuracy

What is sound? Energy Wave, with frequency and amplitude, the frequency level is the tone, the amplitude size is the volume, the sampling rate is the frequency sampling, and the sampling accuracy is the amplitude sampling The frequency range that people can hear is 200-20 kHz, What is codec?

### Basic Idea of Random Simulation and common sampling methods (sampling)

From: http://blog.csdn.net/xianlingmao/article/details/7768833 Introduction We will encounter many problems and cannot use the analytical method to obtain the exact solution. For example, the formula is special and cannot be solved. In this case, you need to find a method to obtain its approximate solution, and have a means to measure the approximate degree of the solution (such as gradual progress, upper and lower limits, or something) Basic Idea of Random Simulation Now let's assume that

### Audio sampling and audio sampling frequency and Bit Rate in MP3

MP3 is only a type of audio format. However, audio has several important parameters, such as kHz, bit, audio channel, and kbps. the formats are different, and the algorithms are different. Therefore, when the above parameters are the same, the quality of different formats varies greatly. VBR is a kind of dynamic sampling. For more information, see the following description. After reading this, you can say something. Audio sample Interpretation Digita

### Random sampling method collation and explanation (MCMC, Gibbs sampling, etc.)

This article is a reference to a number of sampling on the content of the summary + handling, convenient to read their own later. In fact, the information in the material is better than I write, we can look at! Good things to share more! PRML's 11th chapter is also sampling, with time to write to PRML's notes:)BackgroundRandom simulations can also be called Monte Carlo Simulations (Monte Carlo Simulation).

### Opencv-image pyramid-top sampling-bottom sampling

The problem originates from topic 10 in programming Zhu Ji Nanxiong column 12, which is described as follows:How could your select one of N objects at random, where you see the objects sequentially and do not know the value of n Beforehand? For concreteness, what would you read a text file, and select and print one random line, when you don ' t know the number of Lines in advance?The problem definition can be simplified as follows: How do I randomly extract a row from a file without knowing the

### Sampling method for TensorFlow: Candidate sampling

Sampling Introduction If we have a multi-classification task or a multi-label classification task, given a training set (Xi,ti) (x_i,t_i), where Xi x_i represents the context, Ti t_i represents the target category (there may be multiple). You can use the Word2vec negtive method in sampling for example, Use the Cbow method, which is to use context Xi x_i to predict the central word (a single target ti t_i),

### Latin Super Cubic sampling Latin hypercube Sampling,java code

When a random sample is generated, there is a problem of excessive data aggregation, which is solved by the Latin hypercube sampling.The following diagram illustrates the difference between the two:It can be seen that most of the data in the simple random sampling are in the middle, while the Latin cubic sampling is evenly generated in each small interval. Latin cubic s

### API for checking Hardware Multi-sampling capability with multi-sampling and dx11

The display is composed of discrete grids, so there is a "sawtooth" in the display of the image. To solve this problem, people think of a way to "anti-aliasing )". It is called "supersampling", and it works in the same way as its name. It requires "super" capabilities to work well. when this technique is used, the sizes of "back buffer" and "depth buffer" are set to X times the screen resolution. then the 3D scenario is rendered to the backup buffer. When the backup buffer content is displayed o
