Signal compensation (pre-emphasis, de-emphasis, equalization)

Pre-emphasis is a signal-processing technique used at the transmitting end to compensate for the high-frequency components of the input signal. As signal rates increase, the signal suffers significant degradation during transmission. To ensure that the receiving end captures a cleaner signal waveform, it’s essential to restore the degraded signal—this is where pre-emphasis comes in. The core idea behind pre-emphasis is to boost the high-frequency content of the signal at the beginning of the transmission line, counteracting the excessive attenuation these high-frequency components typically experience as they travel. Importantly, pre-emphasis has no impact on noise levels, thereby effectively improving the output signal-to-noise ratio.

How video image colors are processed

A color mode is a model that represents a specific color in digital form—or, in other words, a method for recording the colors in an image. The main color modes include: RGB mode, CMYK mode, HSB mode, Lab color mode, Bitmap mode, Grayscale mode, Indexed Color mode, Duotone mode, and Multichannel mode.

High-Speed Signal Return Current and Signal Integrity Analysis

The signal return path, also known as return current, refers to the flow of high-speed digital signals during transmission. The signal travels from the driver through the PCB trace to the load, and then returns directly—via the shortest possible path—to the driver end, either through ground or power. This returning signal on the ground or power plane is what we call the signal return path.

Standards, Properties, and Measurement of Light Wavelengths

In 1982, the Consultative Committee for Length (CCDM) of the International Bureau of Weights and Measures recommended several laser spectral lines as wavelength standards, such as the wavelength of 339 pm for the methane-stabilized helium-neon laser in a vacuum, and 633 pm for the iodine-stabilized helium-neon laser, also in a vacuum.

Impedance Classification and Its Standards

Impedance Standard: Impedance, defined as the ratio of AC voltage to current, is known as the active definition of impedance. Alternatively, impedance is also an intrinsic property of materials and substances, whose magnitude can be calculated based on their geometric shape and the electromagnetic characteristics of the surrounding space—this is referred to as the passive definition of impedance. The latter approach, being directly tied to fundamental physical quantities, is particularly well-suited for establishing metrological standards.

Video Signal Quality Testing Method (Eye Diagram Measurement)

An eye diagram is a graphical representation formed by accumulating multiple digital signals on an oscilloscope, revealing rich information. From the eye diagram, you can observe the effects of intersymbol interference and noise, providing insights into the overall characteristics of the digital signal—and thus enabling an assessment of the system's performance. As a result, eye diagram analysis lies at the heart of signal integrity evaluation in high-speed interconnect systems. Additionally, this graphic can be used to fine-tune the characteristics of the receiving filter, helping to minimize intersymbol interference and enhance the system's overall transmission performance.
