Y6T50 Optical Module Reception and DSP Processing

Y6T50 Optical Module Reception and DSP Processing

Following yesterday’s discussion, coherent reception involves receiving signals with different polarizations and phases.We expect the ADC sampling to yield results as shown in the figure below, with four phases for one polarization state on the left and four phases for another polarization state on the right, clean and clear, as shown in Figure 1.However, in … Read more

Working Principle of Accelerometers

What is a Sensor? A sensor is essentially a device or apparatus that can “convert physical quantities.” To obtain information for detection and control, it is necessary to convert the state, properties, and physical changes of an object into electrical quantities, using various physical laws for this conversion. Representative physical quantities that sensors detect and … Read more

How the Top 10 Global Analog Chip Leaders Are Formed

How the Top 10 Global Analog Chip Leaders Are Formed

All data originates from analog signals. Analog chips are integrated analog circuits used to process analog signals. Analog signals are continuous in both time and amplitude, while digital signals are discontinuous in both time and amplitude. External signals are converted into electrical signals by sensors, which are analog signals, and further processed in systems composed … Read more
