Electromagnetic compatibility (EMC) is a key indicator for measuring electronic products. The layout of the PCB, the arrangement of components, etc., can act as both sources of interference and targets of interference. Reducing and mitigating these electromagnetic interferences is crucial for enhancing the electromagnetic compatibility of products. This article discusses the design aspects of PCB … Read more
Image Smoothing Image smoothing (blurring the edges of an image through integration processes) The process of suppressing noise and improving image quality is called image smoothing or denoising. This can be performed in both the spatial domain and the frequency domain. Spatial filtering modifies the image by replacing the value of each pixel with a … Read more
During the research and development process, we discovered that when the robot walks indoors, each step it takes on the floor produces a distinct “thud” sound. A quiet space acts like a natural “amplifier,” making this footstep sound particularly jarring. As robots enter homes, the noise issue becomes even more sensitive, prompting us to consider … Read more
In a DC-DC power circuit, the layout of the PCB is crucial for the implementation of circuit functionality and achieving good performance metrics. Today, we will take the Buck circuit as an example to analyze how to perform a reasonable PCB layout and the considerations in the design. ↓ Click to watch the video explanation … Read more
An oscilloscope is a powerful tool and is arguably the most commonly used device by electronic engineers or anyone looking to measure the electrical characteristics of electronic devices. However, you need more than just an oscilloscope; you also need at least one probe. When selecting a probe, consider the following information: ensure that the probe’s … Read more

There are many types of Bluetooth headphones, including in-ear, semi-in-ear, over-ear, ear-hook, and ear-clip styles. Each has its own advantages and disadvantages: in-ear and over-ear headphones are suitable for immersive music listening and have strong noise-canceling capabilities. However, in-ear headphones can put pressure on the ear canal, and over-ear headphones can be heavy, making them … Read more
