How do you measure input and output impedance?
Input resistance is a measure of the amplifier’s effect on the signal source. The larger the input resistance, the smaller the current taken by the amplifier from the signal source, and the larger the signal voltage obtained at the input terminal of the amplifier,
Tips and PCB Design Guidelines for EMI & EMC
The sensitivity of electronic equipment is getting higher and higher, which requires the anti-interference ability of the equipment to be stronger and stronger, so PCB design has become more difficult

The routing of PCB LAYOUT will be explained from three aspects: right-angle routing, differential routing, and serpentine routing.Today author from QiHe smt pick and place machine discussing about it with you . Right-angle routing (three […]
Introduction to Microcontrollers
The selection of single-chip microcomputer is an important and troublesome thing. If the type is selected properly, the product will be cost-effective and work stably; otherwise, it may cause excessive product cost or affect the normal operation of the product, and may even fail to meet the pre-design requirements at all.
What is the basic knowledge of LED lighting?
LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work?
What are the functions of a resistor?
Resistance (resistance), we often call it R in daily life, the unit is ohm, if you want to define the resistance, it is the size of the resistance of the conductor to the current,
