What is the impact of load capacitance on the output parameters of IC (CMOS and TTL)?

I can't find information on this issue (only found a definition and there is nothing about the output voltage or current). You can throw literature, or at least give a direction in what side to drip.

No picture on monitor, what's the problem?

Good day, nick. Start from the beginning. Generally any old iron, a lot of dusty computer components and nothing better to do I decided to collect some sort of computer out of this, not very much bothered about the dust I gathered from what he found sistemnik old 2-core AMD x64 5000+ 2 gig DDR 2 RAM, 400w PSU on and what o...

How exactly does this pull-up resistor?

Hello. Explain, if possible, how exactly does this pull-up resistor? He goes to the Reset input of the microcontroller. Way I see it, when the power supply is restored (in my case 3.3 V) it pulls the voltage on the Reset input signal is always kept high level (even with a mild voltage fluctuations power supply). Accordingl...

What kind of a legend in the R? Why are the resistors on the output connector?

1. Connect j-tag interface to MK. What is the symbol of the resistor? 2. This is an example completed tasks (probably the wrong). Here are the other values in R. they are chosen? And yet, everywhere resistors with a power dissipation of 0.125 W. Why? For what? Why these? 3. And that's the end of the connector through wh...

Why multimeter readings when measuring resistance constantly jump and reset and can not give accurate result?

Bought a elitech 100 mm multimeter with probes included. When measuring the resistance value is constantly jumping and reset, can not give the final result. Continuity test works through time. I think it's the probes that came in the kit, but this is just my guess. The problem is whether to buy new probes. If so what? It is...

How to place decoupling capacitors? What was the fix?

According to the Datasheet for the MK: capacitors C1-C7, the Datasheet on the sensor: capacitors C8, the Datasheet for the radio module: capacitors C9,C10. As you can see, I just placed them parallel to one another. Is it right? If not, how to do it right? Thank you for your attention.

Why a resistor on the input? How do you choose the values of resistance and resistors?

I need to get to MK, quartz resonator for 16 MHz. Already ready version of the job I found the inclusion. Capacity for filtration, as I understand it. Why a resistor on the input? And actually, based on what and how to select the values of these capacitances and resistance?

What is the resistance of the resistor in the picture?

What is the resistance of the resistors R32 and R33? Other 10K - 10 ohms, and those without the prefix. It's just Ohms?

How is the sensor (the chip?) at E3 (According to ESKD)?

As indicated by the ready sensor (chip?) on the circuit diagram according to ESKD? ( in GOST 2.743-91 not found the answer). In one video seen, what do the "D", but in the cscd of such designation no. Tell me, please!
