There are many key indicators for measuring the quality of an oscilloscope testing system, and the “Effective Number of Bits (ENOB)” is crucial for understanding the entire measurement system. This article will discuss the effective bits of oscilloscopes, the impact of ENOB on actual signal testing, and provide methods for solving it using EXCEL in … Read more
“Analyzing the working principles of digital-to-analog converters and analog-to-digital converters—from resistor ladder networks to Delta-Sigma modulation techniques.” Microcontrollers are “consuming” the entire world. Nowadays, even the most basic tasks like blinking an LED are cheaper and simpler with microcontrollers than building oscillating circuits with discrete components or relying on the once ubiquitous 555 timer chip. … Read more
Ground Noise Isolation and Reduction Solutions for High-Precision ADC Circuit PCBsHigh-precision analog-to-digital converters (ADCs) are widely used in industrial measurement, medical devices, and high-precision instruments. However, in actual circuit design, the performance of ADCs is often affected by PCB layout and ground noise, leading to signal distortion, reduced resolution, and even data errors. Therefore, reasonable … Read more
Suddenly got stuck, what did I learn? Let me ask you, what is the maximum input conversion range of an ADC? (You can answer that in your mind, I can’t hear you), suddenly I was lost, what is it? This is the problem that this short article addresses.The ADC converts the input analog signal into … Read more

The multimeter, also known as a multifunction meter, three-in-one meter, or universal meter, is a versatile and multi-range measuring instrument. Generally, a multimeter can measure direct current, direct voltage, alternating voltage, resistance, and audio levels. Some models can also measure alternating current, capacitance, inductance, and certain parameters of semiconductors (such as β). 1. Structure of … Read more
0 Introduction Before discussing Analog to Digital Converters (ADC) and Digital to Analog Converters (DAC), let’s first clarify what analog signals and digital signals are. Analog signals can be understood as physical quantities from the real world, but these quantities are electrical signals. For example, radio signals, etc. The characteristics of analog signals are that … Read more
With the popularity of electronic products, there is a growing demand for digital systems to connect with the analog world to achieve changes, leading to an increasing need for Digital-to-Analog Converters (DACs). While designers are familiar with traditional voltage output DACs, many applications require current output DACs to provide precise, stable, high-resolution currents (tens or … Read more
