What is pulse width, and what does pulse width mean?

Pulse width is an abbreviation for pulse width, and pulse width has different meanings in different fields. The usual pulse width refers to the period that the pulse lasts to reach its maximum value in the electronic domain.

The maximum value that can be achieved by a pulse is called the "pulse width". Shape, amplitude and width are the main parameters of the pulse. The number of pulses per second that repeats periodically is called the "pulse frequency", and the reciprocal number is called the "pulse period".

Frequency, which is the number of times a periodic change is completed in time, is a quantity that describes the frequency of periodic motion, and is commonly represented by the symbol f or , the unit is one second and a minute, and the symbol is s-1.

The frequency of alternating current refers to the number of times it periodically changes per unit of time, and the unit is hertz (Hz), which is reciprocal to the period. The frequency of alternating current in daily life is generally 50Hz or 60Hz, while the frequency of alternating current involved in radio technology is generally larger, reaching the measurement of kilohertz (khz) or even megahertz (MHz).

Pulse width is the abbreviation of pulse width, which is the time that the high level lasts, and is often used as a sampling signal or a trigger signal for components such as thyristors.

The pulse width is determined by the period and duty cycle of the signal, and is calculated as pulse width w=t p (t: period, p: duty cycle).

Pulse width refers to the duration of a pulse in a pulsed signal, usually expressed in units of time (e.g., nanoseconds, microseconds, etc.). In the fields of electronic engineering, communication engineering, automatic control, etc., pulse width is an important parameter, which determines the characteristics and use effect of pulse signals.

In digital circuits, pulse width usually refers to the duration of a high or low level in a digital pulse signal. In analog circuits, pulse width usually refers to the duration of a specific interval in an analog signal. In communication systems, pulse width usually refers to the duration of the pulse in the pulse modulation signal, which directly affects the bandwidth and transmission distance of the signal transmission.

Pulse width can be measured using a variety of different methods, including timing measurements, spectrum analysis, frequency domain analysis, etc. In practical applications, the selection of appropriate pulse width measurement method can effectively improve the transmission efficiency and use effect of pulse null key signal.

Pulse signalThe narrower the pulse width, the wider the signal bandwidth. SignalPulse durationRefers to the pulse width (time) of the pulse signal. Signal bandwidth refers to all the frequency components (frequencies) that a signal contains.

There are many areas of bandwidth application, which can be used to identify the data transmission capacity of signal transmission, the amount of data passing through the link per unit time, and the display ability of the display. In the analog signal vertical drying system, it is also called bandwidth.

It refers to the amount of data that can be transmitted at a fixed time, that is, the ability to transmit data in a transmission pipeline. Usually in cycles per second or hertz.

hz).

Applications

1. Indicates the width of the frequency band.

The bandwidth of a signal state is the range of frequencies occupied by the various frequency components that the signal contains. Bandwidth is especially important for basic output-to-system (BIOS) devices, such as fast disk drives, which are hindered by low-bandwidth buses.

2. Indicates the ability of the communication line to transmit data.

1. The "highest data rate" that can be passed from one point in the network to another point in a unit of time. A more figurative metaphor for the concept of bandwidth is the highway. The amount of data that can be transmitted on the road per unit time is bps (bit per second).

The bandwidth of a computer network refers to the maximum data rate that the network can pass, i.e., how many bits per second.

2. Strictly speaking, the bandwidth of the digital network should use the baud rate.

to express (baud), the number of pulses per second is expressed in the table. Whereas bits are units of information, due to the binary used by digital devices.

Then the amount of information carried by each level is the logarithm of 2 with 2 as the base.

If it is a ** system, it is a logarithm of 4 with 2 as the base, and the amount of information carried by each level is 2.

Signal pulse width. Refers to the pulse width (time) of the pulse signal.

Signal bandwidth refers to all the frequency components (frequencies) that a signal contains.

From an academic point of view, pulse width is the time width of the current or voltage that changes regularly with time, and the usual research is mainly square waves.

Triangular waves, sawtooth waves, sinusoidal functions.

waves, etc., these waveform changes have a certain regularity, and the square wave generally does not say the pulse width, but the duty cycle.

That is, the ratio of the time occupied by the pulse to the total time during a continuous working time.
