interface. 2. Ultrasonic emission CircuitThe four sets of Transmit circuits of the Four-channel Ultrasonic Flaw Detection card are identical and work in time-sharing mode. Generally, the four transmit circuits are set to work repeatedly, the repeat frequency and probe activation sequence are set by the user in the main interface parameter setting item of the microcomputer based on the specific conditions such as the thickness of the steel plate, and imported into the control system of the Ultr

the two sides are the power supply. The steering gear is 0 ~ according to the signal pulse length of the signal line ~ 180 degrees of fixed point rotation. To control the left and right sides, the upper and lower latitudes, two Steering gears are required. The signal of the steering gear is very simple. The signal period is 20 ms, and there is a short high-level time in each cycle, that is, the pulse. The

Server data storage security is an important part of ensuring the normal operation of servers, and is also the core of enterprise network information construction. The management staff of each company attaches great importance to the important data stored on the server, including: confidential Office documents generated during various management processes, customer data accumulated during business operations, important documents involved in R D, etc. Users always pay attention to the running st

In the second-level return to the first day, you can enter the "I Tao Tian", the Heaven and Man to cultivate the fairy child repair certificate. Inner and inner are having the same frequency and common rate, and have already touched the pulse of heaven. My heart is perfect, and my

without being exposed to the environment. 1. The white armor is displayed as the deck is partially or completely white, and the pressure is not fading. If the deck is spotted, linear, and flake white spot, it is called White Spot Disease. White spots often occur in the half-month of A. As the deck grows, the white spots gradually move forward to the jiayuan. If there is a slight trauma and meridian, and qi and blood cannot benefit, no treatment is required. If it is the primary White Spot, ther

PCM (pulse codemodulation----Pulse Code modulated recording). The so-called PCM recording is the sound and other analog signals into the symbolic pulse column, and then recorded. PCM signal is a digital signal composed of [1], [0] and other symbols, without any coding and compression processing. Compared with analog signal, it is not susceptible to the clutter an

In the previous article, "Wintel IoT platform-windows IoT starter Guide", we explained the setup of the Windows on device hardware preparation and software development environment, as well as a presentation of the Hello Blinky project. At the beginning of this article, we enter the project practice section.Because Windows on device is designed with Galileo as the hardware platform, its peripheral interface is also compatible with the Arduino standard. In addition, the programming model also refe

through string/conversion, after Fourier transform FFT, the signals in the time domain are converted to the frequency domain. After the signals are demodulated and converted in string, the signals are restored to a serial output sequence. O-OFDM Working Principle 2. Optical OFDM signal transmission in Optical Fiber The model of OFDM signal transmitted in optical fiber can be described using the nonlinear schörördinr equation (NLSE: Nonlinear schörör Equation Formula: A (z, T) is the slow a

Introduction to input CaptureThe input capture mode can be used to measure the pulse width or measurement frequency. STM32 timers, in addition to TIM6 and TIM7, have input capture capabilities for other timers.STM32 input capture, simply by detecting the edge signal on the TIMX_CHX, when the edge signal jumps (such as rising edge/falling edge), the value of the moment timer (timx_cnt) stored in the corresponding channel capture/comparison register (TI

. Under the action of alternating electric field, capacitor losses are not only related to leakage loss, it is also related to the periodic polarization establishment process. Film CapacitorAt present, a large number of plastic film capacitors are made of polystyrene, polyethylene, polypropylene, PTFE, polyester (polyester), polycarbonate, composite film, etc.1. cl21/cbb21 Metallic Film Capacitor (CL21-B/CBB21-B metallic film box type), the use of metallic polyester/polypropylene film as the

The audio signal is sampled at a regular interval, called the sample rate, and then quantized to discrete values within a Particular range depending on the bit depth. For example, for 16-bit PCM, the sample values is integers between-32768 and

Troubleshooting prompt: If the c416 (470pf/2kv) in the 48-pin external Sandburg pulse circuit of om8838 is disconnected, the vibration is triggered. The fault is mostly caused by c416 damage. Because c416 is close to the heat source, it is easy to fail. Fault Phenomenon 7: yinjia series (om88
