Using 74HC4051, the eight inputs are connected together to a sine signal (only for testing so the inputs are connected together), and the sine signal measured at the output is as shown in the figure, ...
I have a very small and thin PCB I am trying to design to work in a very small space. Essential trying to only solder a SOT-23 to another SMD chip, hoping to mount them on either side of a double laye...
Hi, I'm an electrical engineer major college student and I want to go into PCB design. I don't know much literally just started searching up things and I'm not even familiar with term...
Why is there a resistor and capacitor connected in parallel at both ends of the microphone (the part circled in red)? What is the role of these two components here? Can they be removed?
The circuit board I made is powered by the USB port of the computer. I feel that the voltage should be relatively stable. Is it necessary to add a voltage regulator circuit? I wanted to add a 7805 thr...
In a double-layer board circuit, if the top layer is covered with GND and the bottom layer is covered with VCC, how will this copper laying method affect the circuit and is there a simulation solution...
36. about power laying copperAnalog ground, power supply and digital ground, power supply is not the same, in the negative layer isolation. Double-click the isolation area to add a network.37.&n...
16. Object class manager: DCDC, here you can add the class of PWR, and add the power supply VCC, GND into the member list. Back to the PCB, the top layer to the bottom layer28. CrystalCrys...
