A multimeter is a common measuring instrument for voltage, resistance, capacitance, temperature, and more. The digital multimeter is easy to operate, rich in functions, and the display screen directly shows the required measurements for DC voltage, AC voltage, DC current, AC current, resistance, capacitance, etc. Today, we will take the clamp multimeter as an example … Read more
A multimeter is an instrument that can measure various parameters, such as alternating current (AC) or direct current (DC) voltage, AC or DC current, resistance, temperature, capacitance, and more. Modern digital multimeters have adopted digital and logic technologies, becoming smaller in size and featuring more built-in functions. By introducing digital technology, digital multimeters can provide … Read more
Oscilloscope, as its name implies, is a machine that displays waveforms, and it is also known as the “eye of the electronic engineer.” Its core function is to display the actual waveform of the measured signal on the screen, allowing engineers to locate problems or evaluate system performance, among other tasks. Its development has also … Read more
Oscilloscopes Are Simple Yet Complex! But Why Are Oscilloscopes So Expensive? Most cost thousands or tens of thousands, why are they so expensive? Structure of Digital Oscilloscopes The Reason Oscilloscopes Are Considered Simple Is That An Oscilloscope Is A Test Instrument That Can Display The Dynamic Waveform Of Voltage Signals. An Oscilloscope Converts Time-Varying Voltage … Read more
Written by/ Shi Bin, Tang Mingze Under the impact of television, broadcasting has gained a “revival” due to the popularity of cars, thus broadcasting is also referred to as “media on wheels.” Entering the digital network era, especially with the continuous maturity of 5G network communication technology and Internet of Things technology, the “Internet of … Read more
Antibody drug conjugates (antibody drug conjugate, ADC) are a class of emerging targeted anti-cancer drugs that have shown excellent efficacy in clinical trials against various refractory and metastatic solid tumors. However, the therapeutic effects and potential biological mechanisms of ADC drugs used in combination with other targeted therapies remain unexplored. Recently, Researcher Guo Peng from … Read more
1. Basic Principles and Classification of D/A Converters T-type Resistor Network D/A Converter: 2. Correspondence between Output Voltage and Digital Quantity 3. Main Performance Indicators of D/A Converters 1. Resolution Resolution refers to the change in the corresponding output analog quantity (voltage or current) when the least significant bit (LSB) of the input digital quantity … Read more
Protein Hydrolysis Targeted Chimeras (PROTAC) are bringing revolutionary changes to the fields of biology and medicinal chemistry. PROTAC consists of a target protein ligand, an E3 ligase ligand, and a spacer group[Unlike the linker used in antibody-drug conjugates, here we specifically use “spacer” instead of the commonly seen “linker” in PROTAC literature]. PROTAC structural composition … Read more
To deliver chemotherapy drugs more effectively, small molecule drug conjugates (SMDC), antibody-drug conjugates (ADC), and degrader-antibody conjugates (DAC) have been explored and developed, providing selective delivery while improving the therapeutic index. What are their similarities and differences? What are their respective advantages? What is the current state of research? What does the future hold? This … Read more
In electronic design, the layout and routing of Analog-to-Digital Converters (ADC) and Digital-to-Analog Converters (DAC) are key factors affecting system performance. Proper routing can not only improve signal quality and reduce noise interference but also optimize the overall performance of the system. 1. Pre-define Routing Areas 2. Separate Analog and Digital Signals 3. Optimize the … Read more
