What is the purpose of the pulse What is the purpose of the pulse

It has long been said that the development of electronic pulses **. Use electronic pulses to kill enemy electronic equipment and destroy**.

A pulse usually refers to a short, fluctuating electrical shock (voltage or current) that resembles a pulse, which is often used in electronic technology. The main characteristics are waveform, amplitude, width, and repetition rate.

A pulse is a signal that occurs for a short period of time relative to a continuous signal over the entire signal period, and there is no signal for most of the signal period. It's like the pulse of a person. Now it generally refers to a digital signal, which is already a signal half the time in a cycle.

The signal in the computer is the pulse signal, also known as the digital signal. In addition, pulses are also used to indicate thoughts and emotional impulses and demands.

From the definition of pulse, it is not difficult to see that pulse has the characteristic of spacing, so we can think of pulse as a signal. The definition of the pulsed signal arises from this:

In contrast to continuous signals (signals that are present for a short period of time throughout the signal period), most pulsed signals have no signal for a period of time. It's like the pulse of a person. A pulse signal is generally a digital signal, which is already a signal for half the time (or more) of a cycle.

The signal in the computer is the pulse signal, also known as the digital signal.

Pulses are brief undulating electrical shocks.

A pulse is usually a type of electrical shock (voltage or current) that fluctuates briefly like a pulse that is often used in electronic technology, and its main characteristics are waveform, amplitude, width, and repetition rate. Programs that utilize pulse shaping can produce different pulse shapes, and depending on the application, the optimal pulse shape will vary.

Electronics

Electronic technology refers to "related technologies containing electronic, data, magnetic, optical, electromagnetic, or similar properties", and the so-called "electronic form" refers to the form of information that cannot be directly perceived by human sight or hearing and must be converted with the help of a certain carrier.

The so-called electronic technology can be divided into two parts: analog electronic technology and digital electronic technology. Analog electronic technology is the foundation of the entire electronic technology, and has an irreplaceable role in the fields of signal amplification, power amplification, rectifier regulation, analog feedback, frequency mixing, and modulation and demodulation circuits. For example, high-fidelity (Hi-Fi) loudspeaker systems, high-frequency transmitters in the field of mobile communications, etc.

Compared with analog circuits, digital circuits have a series of advantages such as high precision, good stability, strong anti-interference ability, and program software control. Judging from the current development trend, except for some special fields, the application of some analog circuits in the past has a tendency to be gradually replaced by digital circuits, such as digital filters.

Chongmai is one of the eight meridians of the human body.

The pulse can regulate the qi and blood of the twelve meridians, so it is called the sea of the twelve meridians.

It is closely related to reproductive function, and can be excreted normally during menstruation, so it is also called the sea of blood.

It starts in the cell, goes down to the perineum, and joins the Zushao Yin meridian from the Qi Street, clips the umbilicus upward, spreads into the chest, reaches the throat, and surrounds the lips.

Physiological function of the pulse (1) Regulate the qi and blood of the twelve meridians: the pulse is up to the head, down to the feet, running through the whole body, and is the key to leading the qi and blood of the meridians.

When there is a surplus of qi and blood in the meridians and viscera, the pulse can be stored and stored; When the meridians and organs are deficient in qi and blood, the pulse can be perfused and supplemented to maintain the normal physiological activities of various tissues and organs of the human body.

Therefore, it is known as "the sea of twelve meridians", "the sea of five internal organs" and "the sea of blood".

2) Main reproductive function: The pulse originates from the uterus, also known as "blood room" and "blood sea".

Pulse has the effect of regulating menstruation.

Chongmai is closely related to reproductive function, and women are "too chong mai is prosperous, and menstrual affairs are in the present, so there are children."

The pulse of Taichong is weak, and the heavens are exhausted and the earth is impassable.

The "Taichong pulse" mentioned here refers to the chong pulse.

In addition, in men, either the congenital pulse is not filled, or the acquired pulse is injured, which can lead to the decline of reproductive function.

3) Adjust the rise and fall of the qi machine: the pulse is in the circulation and is in the foot less yin, which belongs to the yangming, and is also connected to the yin and the sun.

Chongmai has the function of regulating the rise and fall of qi in certain organs (mainly liver, kidneys and stomach).

In signal processing, pulse has two meanings:

1) A rapid transient change in the amplitude of a signal, from the reference value to a higher or lower value, and then quickly back to the reference value.

2) A rapid transient change in signal characteristics (such as phase and frequency), from the reference value to a higher or lower value, and then quickly return to the reference value.

A pulse is a short, undulating electrical shock like a pulse, usually a process in which a physical quantity rapidly returns to its initial state after a sudden change in a short duration. Pulses occur for a short period of time relative to a continuous signal throughout the signal cycle, and most of the signal cycles have no signal, just like a human pulse.

The characteristic parameters of the pulse include pulse amplitude, pulse width, pulse rise time, pulse fall time, pulse period, pulse frequency, and so on.

Common pulse signals include non-sine wave signals such as busheng rectangular pulse, square wave pulse, sharp pulse, sawtooth wave, bell wave, stepped wave, trapezoidal wave, and triangle wave.

Pulse technology is widely used in various fields such as electronic computer limb, communication, radar, television, automatic control, telemetry and remote control, electric navigation, measurement technology, etc., and has become an important part of various electronic systems.

A negative pulse is a signal that jumps from high to low and then from low to high. That is, the negative pulse is a falling edge first, then a low level and then a rising edge. A pulse includes both the rising edge and the falling edge of the sail cavity.

A pulse signal is a discrete signal with a variety of shapes, and compared to ordinary analog signals (such as sine waves), the waveforms are discontinuous in the time axis (there is a clear separation between waveforms) but have a certain periodicity. The most common pulse wave is a rectangular wave.

Application of pulse technology.

The non-linear conversion circuits widely used in pulse technology include Schmidt triggers, monostable flip-flops and bistable flip-flops. The Schmidt trigger can be used to convert the input signal of any waveform, such as a sine wave and a three-state return angle wave, into a rectangular pulse with a steep edge.

Monostable flip-flops can be used to generate a signal with a specific pulse width based on one side of the input pulse (rising or falling). The bistable flip-flop can divide the input pulse to form various counters, dividers, and so on.

Pulse technology is widely used in various fields such as electronic computers, communications, radar, television, automatic control, telemetry and remote control, radio navigation, measurement technology, etc., and has become an important part of various electronic systems.
