How Can You Identify the Main Causes of Noise in an Analogue Circuit?
Hi everyone,

I'm interested in understanding how engineers approach noise problems in analogue circuits, particularly when the source of the noise isn't immediately obvious.

When reviewing a circuit, what do you normally check first? For example, grounding, power-supply noise, component selection or the layout of signal paths?

How can you n...

What if battery is always connected to the charger?
Hello, I have some systems where power supply is reserved by battery. Mainly I am speaking about 3.7 and 3.2 batteries 18650 (26650), for these purposes are used chargers TP4056 and CN3058E respectively.
Is it ok that battery connected to it in a constant manner? According to the datasheet, in controller there is 1/10 CC termination procedure. So normally, nothing bad shou...

Advice needed for converting 6 volt dc lantern to 120 volt power supply
I have 5 NEBO 100 lumen Retro Lanterns that I would like to convert to 120 volts. Each lantern has a battery pack of four AA batteries which is 6 volts dc. These lanterns will be placed about 5 feet apart. Is there a way I can connect all of them to one power source instead of having one converter for each lantern? I also want to have some kind of connection where they can be un...

4060 counter doesn't stop ?
I have a timer switch using the cmos 4060 counter and the NE555 ic , which i replaced both of them.

I checked the potentiometer supposed to be 1 Mega ohm but has only 0.7 kilo ohm connected to pin 10 or 11.
Maybe should be 1 Meg straight.

Any ideas ? Because the switch is supposed to open after 10 minutes ?
