what is Receiver? what is Receiver? The electromagnetic signal received by the antenna is sent to the receiver.The ideal receiver inhibits all unwanted noise, including other signals, and does not add any noise or interference to the required signal.Regardless of the form and format of the signal, it can be transformed to fit the desired characteristics of the signal processor detection circuit and then to the intelligent user interface. structure The receiver has two basic structures, one is superhetrodyne structure and the other is the direct transformation structure. A superheterodyne receiver, is the received radio frequency signal with a frequency of the vibration signal mixing or next after frequency conversion output frequency of a low intermediate frequency modulation signal . The frequency of the intermediate frequency signal is the fixed frequency difference between the oscillator signal and the frequency of the received signal. The demodulation of the final si

            What's its function? What's its function? Micro-projector also known as portable projector. Micro-projector make the traditional large-scale projector more compact, portable, miniaturization, entertainment, practical, so that projection technology closer to life and entertainment. Equipped with the business office, teaching, travel business functions instead of television Working principle:The main working principle of the projector is to make light from the light sources, through a series of optical lighting system to make the light source evenly on the display chip, and the signal through the circuit system in the display chip to achieve color and gray scale, display the image, then the enlarged image displayed in corresponding screen by the front projection lens. In the projection system, the optical is mainly divided into imaging optics and lighting optics, and one of the most critical components are the display chip and lighting components (ie lig

            Introduction to FPV Systems Affordable FPV systems have appeared within the last decade. FPV system flying is a rapidly growing trend in the various RC hobbies, and for good reason; it takes the beauty and energy of flying, driving, piloting a boat, and packages it in a relatively safe and less costly package. For many, this is the draw of flying rc models. Until recently, however, setting up an FPV system has been very time consuming and required a lot of technical skills. Now we have companies such as flysight bringing a ready to fly, FPV multirotor to the masses, requiring no prior knowledge. While it may be more convenient to buy flysight F250, plug in your tablet, and fly, it is still crucial that you know how these FPV systems work. The current technology boom keeps this subject alive and forever interesting! Screens, goggles and glasses continue to evolve. Video transmitters and receivers have improved and become more reliable. Antennas and antenna tracking

  2017 Best Selling Portable Outdoor Mini Wireless Bluetooth Speaker Chine Manufacturer Suppliers Bluetooth speaker is the audio equipment with the built-in Bluetooth chip, using a Bluetooth connection to replace the traditional wired connection, according connect the mobile phone, tablet PCs, notebooks and other Bluetooth playback devices to achieve the purpose of convenience. Definition: Bluetooth speakers are that using the Bluetooth technology in traditional digital and multimedia speakers so that the users can avoid annoying wires tied down, to listen to music freely in a variety of ways. With the development of intelligent terminals, the advent of Bluetooth speakers received widespread concern by the mobile phone tablet and other users. Bluetooth technology (Bluetooth) make the wireless speakers become possible, all kinds of well-known brands have released a wide variety of the "Bluetooth speakers" so that consumers spend about 10 to  3,000 yuan, you can le
