I have several very simple circuits comprising of a battery connected to a LED. Additionally I have an input signal at some frequency, which I need to use in order to control these circuits. What I ...
We know the frequency of a direct current is zero. The reason is that there is no repetitive pattern. But i was stumbled when i notice, why cant that straight line be cut into smaller pieces, and ...
I need to implement a frequency counter (pulses per minute) of a DC circuit that goes up to 20 volts. A little background, I am building a linear power supply 0-20 volts, 0-3 amps for my relative who ...
Just got curious about this last night when I was wiring a couple of LEDs on my brother's long board. For a simple DC circuit (Battery, resistor, LED), how long can I stretch the wire until the power ...
Background information: I tried hard to get a Schmitt-trigger working, but it kept failing. By accident I figured out, that my AC-to-DC adapter produces a very irregular voltage output (I could hear ...
