PCM (Pulse-code modulation) Pulse coding modulation, pcm Pulse Coding modulation In audio processing, we often hear PCM data. What is PCM Data?PCM data is a digital signal after the analog signal passes through PCM. PCM is the process of converting the audio signal from analog signal (time continuous, value continuous) to digital signal (time discrete, value dis

-precision optical pulse sensor. From electrical signals to physiological signals, a new value space for smart hardware is being opened.Unique optical pulse-BO sensorRohm Roma Semiconductor is a well-known global semiconductor manufacturer, since its inception in Japan in 1958 after half a century of development has become a global system IC and leading semiconductor manufacturers, products involved in IC,

First, prefaceA simple pulse synchronizer has been described in the previous article, which allows for synchronization in simple scenarios, as well as a number of application limitations or drawbacks, such as:(1) It is sensitive to the DST_CLK relation of SRC_CLK domain, and may not adapt when the SRC_CLK and DST_CLK clock frequency differ greatly;(2) because there is no complete handshake mechanism, when the interval between multiple src_pulse is sho

[Serialization] FPGA OpenGL series instances Sequence Pulse Generator Based on OpenGL I. Principles In a digital circuit, a circuit that can output pulse waveforms in turn in a certain order of time is called a sequential pulse generator. In digital systems, it is often used to control certain devices to perform operations or operations in the order specifi

The Pulse watt-hour meter provides the functions of collecting power, load monitoring, data transmission and so on for comprehensive automatic substation and remote automatic monitoring.The Pulse watt-hour meter is mainly composed of two parts, the electric energy measurement component and the pulse device.

. 　　 　　 But when we want to emphasize a relationship or thing through this distortion, we can use close-up photography to achieve the goal. For example, the strength of a boxer's punch is exaggerated, and a close-up shot can make that fist gigantic. Each method has its limitations, even if the simple and practical approach we have mentioned above is no exception. Proximity can mean aggression and aggression. If we shoot ani

Custom photography function in CameraAPI, photography by cameraapi A few days ago, the project needed to use CameraAPI to define the camera. The previously used QR code also needed to write the underlying code. Therefore, I would like to summarize some things about using CameraAPI. Currently, the official documents of JDK and later versions no longer recommend using the camera package but the camera2 packag

to the impulse function. (Any linear system was given by integration against a kernel (impulse response).)The derivation process is as follows:$\begin{align*}V (x)= (\delta * v) (x) \ \=\int_{-\infty}^{\infty}\delta (x-y) v (y) dy \qquad (\delta\ shift\ property)\end{align*}$So the linear system has the following representation$\begin{align*}Lv (x)=l\left (\int_{-\infty}^{\infty}\delta (x-y) v (y) dy \right) \ \=\int_{-\infty}^{\infty}l_x\delta (x-y) v (y) dy\end{align*}$Make $h (x, y) = L_x\de

Two methods:1, collect the signal complete waveform, carries on the calculation:Is it possible to select an analog capture card with a 250ks/s sampling rate to display the required waveform?No! We have not considered measuring accuracy 0.1%!Because the analog signal is continuous, the period of the signal is 1/(22.5K) =44.4us, duty cycle accuracy of 0.1%, the signal resolution of at least 44.4us/1000=44.4ns, the sampling rate than 1/44.4ns=22.5ms/ s to be large to measure to meet the accuracy re

One, keep simple There are a lot of techniques to try when photographing people. But one thing to keep in mind is: Don't try too much, just keep it simple. Make the light as simple as possible, make your subjects feel as natural and relaxed as possible, and choose the right equipment, and you will be able to capture wonderful characters. 　　 This picture is simple but impressive. The subject is cheerful and quiet, but the tilted head makes the character feel powerful. Diagonal meth
