strong. (Beautiful, degraded performance)The 4th generation of reversing radar: combined with the previous generations of hybrid, performance and aesthetics have improved, the price is slightly higher. (complex)5th generation reversing radar: Integrated AV system, local tyrants dedicated, rear camera. (High-end models)PS: Left for 2nd generation products, right for 5th generation productsSecond, the principle of radar rangingEven the 5th generation local tyrants package above is based on ultras

means that the low-frequency direct and reflected waves mutually enhanced, producing more bass. Figure 2 shows that in the No-noise room (non-reflective sound room) and the general room to detect the frequency response of different speakers, frequency responses to the picture of the loudness control frequency., not only bass enhancement, but also add the low-frequency extension of the speaker. Close to each side of the speaker, will enhance the outpu

The goal is to change people's mindset and focus on finding the main force. Only by keeping up with the main force can there be a major wave of growth. Chapter 2: Find the main force in qu

a signal with edges and corners, for example, the slope of a non-continuous change occurs in a square wave. It was not until 15 years after his death that the paper was published.Who is right? Returns the right result from the use of the Laplace curve. The Sine Curve cannot be combined into a signal with edges and corners. However, we can use a sine curve to represent it very closely. There is no energy difference between the two Representation Methods. Based on this, Fourier is correct. Why

The two main roles in the film, Captain Jack and Doctor Stephen, seem to imply these two directions: Jack is always enthusiastic about defeating the enemy ship, stephen's pursuit of the mysteries of nature and biological origins is so different between the two friends, but with the journey on the ocean, the ultimate con

slightly lower, and the intensity of speech is at the moderate intensity between the hearing threshold and the maximum audible threshold. 2. Sound transfer between outer ears and middle ears (1) sound collection and resonance cavity effects of ear and external ear canal The outer ear consists of the ear and the outer ear. The Movement Ability of the ear of human ears has degraded, but the front and side sound can directly enter the outer ear canal, and the ear shape is conducive to the

Learning the beauty of mathematics and mathematics Read the beauty of Mathematics In fact, I have been preparing to read the book "The beauty of mathematics" for a long time. I remember reading "the waves of the waves" last summer, and then I met a person like Wu Jun, who liked his writing style. So I am going to read the beauty of mathematics. Like the book "The beauty of mathematics", the book itself has

On the K-line chart, we can often clearly identify the rising waves, three waves, and five waves. On the K-line chart, the stock price ends at the bottom and starts to rise. When the first wave is on the rise

is from the shooting principle. If a laser is used to illuminate a tiny particle. The light waves reflected from small particles are basically ball waves that are constantly expanding outward. We look at small particles as bright. When a camera is used to take a photo of this small particle, light waves form a bright spot on the negative film through the lens. T

The concept of radar was formed in the early 20th century. Radar is a transliteration of radar, abbreviated as radio Detection and Ranging. It is an electronic device that uses microwave band electromagnetic waves to detect targets. Composition The specific use and structure of various radars are different, but the basic form is the same, including five basic components: the transmitter, the transmitting antenna, the receiver, the receiv

required on the sound card. The values are 12.288mhz and 24.576 MHz (or an integer multiple of them ). Audio sampling ad Digital audio systems reproduce the original sound by converting the acoustic waveform into a series of binary data. The device used in this step is A/D) it Samples sound waves at tens of thousands of times per second. Each sampling record the state of the original simulated sound waves
