Filtering is crucial in the field of signal processing, widely applied in communication, electronics, and image processing. Its main function is to filter out interference noise and enhance the energy ratio of useful signals in sample data, thereby achieving a signal-to-noise ratio gain. The mathematical principle can be abstracted as a convolution operation, which is … Read more

The goal of this design is to produce an isolated DAC output. It requires a 12V power supply to generate an output of 0~5V, achieving approximately 13.3 bits of resolution at 10,000 counts. The DAC output must stabilize within 1 second after changing settings, and it should maintain stability and low noise over extended periods. … Read more
The circuit board cannot do without power chips. We generally use a large capacitor (100μF to 1000μF) and a small capacitor (0.1μF or 0.01μF) as the power filtering capacitors.The large capacitor is used to filter out low-frequency noise, while the small capacitor is used to filter out high-frequency noise.You have designed so many circuit boards; … Read more
1. PCB Protection Design Principles• Shielding Measures: Use metal enclosures, conductive coatings, or shielding covers to shield the equipment, reducing electromagnetic radiation and interference.• Grounding Design: Reasonably layout a low-impedance grounding network to avoid ground loop interference, ensuring the device grounding terminal is well connected to the earth.• Layout Optimization: Separate analog, digital, power, and … Read more

Today, we will look at another exciting combination technique in Python. Let’s start with a pure music piece~ filter() is a built-in higher-order function in Python used to filter iterable objects (such as lists, tuples, etc.). By combining it with a lambda function, we can succinctly define filtering conditions. For example, filtering even numbers: numbers … Read more
