Re: Something Wrong with Coupling Capacitor
I think whether this can be regarded as the equivalent series of stopping DC capacitor, so the capacity decreases, the low frequency impedance increases, and the bass becomes worse. If the combination of the front and back stages is not constant, any straight phase can be removed; the combination of...

Something Wrong with Coupling Capacitor
I bought a 5532 front tuning board, with two coupling capacitors on the output side of the tuner, another two resistors at the input end without coupling capacitors, and two coupling capacitors at the input end of the post-stage power amplifier. In this way, there are four coupling capacitors betwee...

Resistor Color Codes
For the resistor color codes, it is necessary to understand the corresponding relationship between the colors and the Arabic number. So I find some material to learn it, the color in different positions has different digital meanings, that is, the colors representing different values( learning from ...

Looking for a Specific IC Embedded Systems
I want to make a hand held device of very small dimensions, which incorporates 4 leds and a motor. I used an 8051(https://www.kynix.com/Parts/2627837/8051%20CONTROL%20BOARD.html) to control these leds and motor and code accordingly, but as size is a constraint I can’t afford to make use of it. The I...

Some questions met when designing PCBs
I've designed a kind of PCB now, but never put much thought into good practices. They were small boards and most of the emphasis was put into just making sure everything connected that needed to be connected. I want to get more serious into making well designed boards currently. I've designed and re...

How to select the Gate Drive Resistor
I am currently doing my graduate paper design about the drive resistor of MOSFET, be specifically, about the gate drive resistor, and I'm trying to figure out how to use the parts which are available from the Internet. Fortunately, I find a article about the calculation, there have formulas and calc...

How select the Commonly Used Electronic Components
Daily contact with electronic components is a common practice for engineers, but for beginners, even if they have information about the type of components they need, it is a headache when they browse the merchants to buy them. The datasheet is the same, and there are some additional reference values...

Re: Need help with a circuit again
I think you must know the component very well and then you may have a test to check it.
So the basic knowledge of your components in circuit you must know, here is the part https://www.kynix.com/Blog/316.html, also you must keep your circuit is correct first.
cheers.
