The Effective Number of Bits (ENOB) of an ADC is one of the key indicators for measuring the actual performance of an Analog-to-Digital Converter (ADC). This article first provides a simple theoretical foundation, followed by examples illustrating how to calculate signal power, noise distortion power, and subsequently obtain the Signal-to-Noise and Distortion Ratio (SINAD) and … Read more
ChatGPT is becoming increasingly powerful A year ago, I was only using ChatGPT to search for some simple example codes and to add comments line by line to my own code, with comments so precise that I was amazed. Now, I can simply describe the desired effect to ChatGPT, or even just send a picture, … Read more
In this issue, we will share how to read data from a CSV file and create plots with a single click. Sometimes, we save data such as spot images or spectra in CSV format, which can be imported into Origin for plotting. However, it can also be easily achieved with just a few lines of … Read more
In the process of image processing and storage optimization, the JPEG compression ratio directly affects image quality and file size. This example demonstrates the implementation of JPEG image compression, intuitively presenting the relationship between image effects and file sizes at different compression ratios. 1. Code %% JPEG compression processing with different quality ratios im = … Read more

Random signals cannot be represented by deterministic mathematical relationships and cannot predict their future instantaneous values. Any observation only represents one of the possible outcomes within its range of variation, and its value changes according to statistical laws. It is not a deterministic function of time, and there is no definite function value at any … Read more
Image color modes correspond to various color spaces, and the conversion and analysis of color spaces are crucial. This example demonstrates various color space conversions and related image processing operations. Estimated reading time: 5 minutes. 1.
