overloaded methods, using Int32 or TimeSpan to define the wait time-out period, and whether to exit from the context's synchronization domain. WaitAll (waithandle[]): This is used to wait for all members in the WaitHandle array. This approach is a good choice if you need to wait for everyone in front of you to finish before you can continue. There are still two overloaded methods to control the wait timeout, see for yourself. WaitAny (waithandle[]): Unlike WaitAll (), WaitAny is returned

Method for Improving the precision of Variable Optical Fiber Delay Line

1 Introduction Nowadays, delay lines have been widely used in signal processing, radar, electronic countermeasure, and other fields. For example, the Unit delay device required for signal processing is a kind of memory, and the dynamic target display (MIT) there must be a delay line-another kind of memory. In electronic confrontation, the signal must be stored for a certain period of time before processing. For example, the receiver's radar signal must be delayed for a certain period of time be

-frequency oscillator, generating high-frequency oscillation signal. This signal is fed into the timing signal generator and generates a sinusoidal signal and a timing pulse signal. The sinusoidal signal is fed into the coded modulator as the carrier signal, and the timing pulse signal is sent to the sweep signal generator, keyed input encoder and instruction encoder as the time standard signal of these cir

Sampling--Quantization--code:Sampling frequency: The Nyquist theory states that the sampling frequency should not be less than twice times the maximum frequency of the sound signal, so that the voice can be restored to the original sound as a digital expression, which is called lossless digitization (lossless digitization) Sampling accuracy: Number of bits per sound sample (bps)Amount of data (Bytes/sec) = (sampling frequency (Hz

Multithreading: C # thread synchronization lock, monitor, mutex, synchronization event and wait handle

on the object to allow other threads to lock and access the object. When other threads access an object, the calling thread will wait. The pulse signal is used to notify the waiting thread of changes to the object state. Pulse (), pulseall () sends signals to one or more waiting threads. This signal indicates that the status of the waiting thread lock object has changed, and the lock owner is ready to rele

Efm32-chip peripherals-external clock of PCNT

In the official Application note, we can see that the PCNT oversampling routine uses a 32 Khz clock source as the reference clock source. There is also an orthogonal code. Although the external signal is used as the clock of the PCNT module, we rarely use orthogonal code. In addition, we can better master this function only when we have used it. Therefore, we still use our STK to understand how PCNT uses external signals as the clock. But one thing to note is that synchronization is a problem. I

The clinical thinking of traditional Chinese medicine is quite different from that of physicians of different genres in different ages. In particular, the clinical thinking of the managers has a certain detached characteristic. Observation of disease, the ch

How PCM works

PCM Definition PCM Chinese called pulse code modulation, composed of. rivers proposed in 1937 that this concept laid the foundation for digital communication. In 1960s, it began to be applied to the local telephone network to expand the capacity, so that the transmission capacity of most existing audio cable core lines was increased by 24 ~ 48 times. By the middle and end of 1970s, various countries have successfully modulated

Duty Cycle, power distribution, and edge distribution

From Baidu Duty Cycle The duty cycle (Duty Cycle) has the following meanings in the telecom field: In a string of ideal pulse sequences (such as square waves), the ratio of the duration of the Positive pulse to the total cycle of the pulse. For example, if the pulse width is 1 μs, the duty cycle of the

CPU: What is the CPU clock speed?

In electronic technology, the pulse signal is a pulse signal continuously sent at a certain voltage range and at a certain interval. The interval between pulses is called a cycle, and the number of pulses generated per unit time (for example, 1 second) is called a frequency. Frequency is the metering name that describes the number of pulses that appear in a periodic cycle signal (including a
