Linear Interpolation and Sinc Interpolation in Oscilloscopes (YUNSWJ Simulation Version)

Linear Interpolation and Sinc Interpolation in Oscilloscopes (YUNSWJ Simulation Version)

There is a passage in the manual that I wonder if everyone has a deep understanding of: About this interpolation Memory Depth Memory depth = the number of sample points that can be saved in one frame of waveform. Formula: SampleTimeSamplePointNumberSampleInterval The larger the memory depth, the longer the time range can maintain a higher … Read more

The Golden Partner of Antihypertensive Drugs: A+C Plan

Mr. Zhao has been suffering from hypertension for over 10 years. In recent years, he has been taking two antihypertensive medications, but sometimes he misses doses, leading to poor blood pressure control. At the pharmacy clinic of Zibo Central Hospital, the pharmacist switched to a single-pill combination preparation using the A+C scheme based on Mr. … Read more

How to Convert DTS to Stereo

How to Convert DTS to Stereo

DTS conversion to stereo DTS is currently one of the high-quality lossless music formats, with DTS5.1, DTS6.1, DTS7.1 and others. DTS files are divided into DTS split tracks, DTS whole tracks, and DTS images. DTS offers a three-dimensional spatial feeling, immersing music lovers in the experience, and is also a form of aesthetic enjoyment. DTS … Read more

Insights on RC Filter Design for SPI Communication

Insights on RC Filter Design for SPI Communication

Introduction In some EMI testing items (such as RE), there may be cases where radiation exceeds standards due to SPI communication. A common solution is to add an RC filter to the SPI communication loop, which can attenuate high-frequency noise to improve radiation levels. However, adding an RC filter can affect the signal quality of … Read more

Collaboration of STM32 and FPGA: Creating a High-Precision Local Control DDS Arbitrary Waveform Generator

Collaboration of STM32 and FPGA: Creating a High-Precision Local Control DDS Arbitrary Waveform Generator

Click the blue text Follow us This article introduces the design and implementation of a local control DDS arbitrary waveform generator based on STM32 and FPGA. The project successfully generates adjustable waveforms (sine, triangle, square), frequencies (DC-5MHz), and amplitudes (0.1V-1V) using a high-speed DAC combined with FPGA internal DDS logic, and displays waveform parameters in … Read more

How to Distinguish Pitch, Loudness, and Timbre from Waveforms

How to Distinguish Pitch, Loudness, and Timbre from Waveforms

1. The Three Elements of Musical Sound 1. Pitch refers to the highness or lowness of a sound, determined by frequency. In physics, the speed of an object’s vibration is described by the frequency, which is the number of vibrations per second. A faster vibration results in a higher frequency and a higher pitch; a … Read more

Audi's Fault: Burning Money Faster than Circuit Boards!

In recent days, several Audi vehicles have come into the shop, all displaying the warning “Battery Voltage Low.” The car owners initially thought, “It’s fine, we can still drive!” But as they drove, the car suddenly broke down and turned into an electric deadweight! Time to call a tow truck! Using a diagnostic tool, the … Read more

Practical Applications of Oscilloscopes: Precise Control of Exposure and Color Cast with Waveform and Vectors

Practical Applications of Oscilloscopes: Precise Control of Exposure and Color Cast with Waveform and Vectors

Our eyes can deceive us, but data never lies. Today, I will teach you how to use DaVinci’s built-in “Oscilloscope Duo”—the waveform and vector scopes—to precisely control the brightness and color of your footage, just like playing a puzzle game. All operations have been tested on the free version of DaVinci 18, so follow along … Read more
