You say "Never forget he was elected by us." Do you have any evidence for this statement? Also, you mention "he nominated himself," then you provide a link to Linux Systems meta that doesn't contain Olin's name. What were you trying to say when you made that link? (more) |

For the second, a capacitance is present whenever two conductors are separated by an insulator. An inductor is usually in the form of a coil. In between the windings of a coil, there is a parasitic capacitance. The core that you mention is not in between the windings of a coil. So it seems that y... (more) |

You seem to have two ideas in your post: (1) resonant frequency, (2) capacitance. For the first, we usually want an inductor to behave mostly as an inductor. If we operate it at a large enough frequency, then it stops being mostly an inductor. If the resonant frequency is 100 kHz, then you would n... (more) |

@#36396, yes, that's the point I was trying to make. I was hoping that the OP would get it. (more) |

Okay. The OP seems to be a student, but I have no problem with your response. (more) |

The way the post is written, it sounds like the OP is thinking of a parallel-plate inductor. Is that correct, @#54107? (more) |

I mentioned in a comment under the posted question that the 1-A current source cannot be connected in series with an open switch. I proposed a way to correct the circuit, but the OP doesn't seem to understand that the original circuit is wrong. Could you perhaps edit your answer to note this? Than... (more) |

With the switch open, there is no current passing through the current source, which contradicts the fact that it is supplying a nonzero current. Perhaps, instead of a switch in series with the current source short circuiting at the start, you meant to have a switch in parallel with the current sourc... (more) |

A: What is the difference between emitter and collector of a transistor? A bipolar junction transistor can be used as an amplifier, in which case some parameters of interest are $\alpha$ (the common-base current gain, equal to $IC/IE$) and $\beta$ (the common-emitter current gain, equal to $IC/IB$). (Here, $IC$, $IB$, and $IE$ are the currents at the collector, base, and... (more) |

If by "mode" you mean "stable state," then for "one mode" you might be interested in [monostable multivibrators](https://en.wikipedia.org/wiki/Monostable_multivibrator). (more) |

It is not clear to me what you do know and what you don't know. You should edit your post to reflect these. Do you know how to make a sequential circuit? For example, do you know what a state diagram is and what a finite state machine is? (more) |

A: Division of binary numbers logic circuit You're thinking of a digital comparator, "a hardware electronic device that takes two numbers as input in binary form and determines whether one number is greater than, less than or equal to the other number." (more) |

What I mean is, if the chip you suspect is fake outputs a "quiescent output voltage at pin 4 of about 850 mV," then what is output by a real AD8307? (Not just in theory, but in practice.) (more) |

Do you have a "real" AD8307? What is its output at pin 4 for this circuit? (more) |

Thank you for your answer. It has given me lots of insights. I use this circuit when I give exercises in writing structural VHDL code. (It's not a circuit that already has existing code available on the internet.) (more) |

| Question | — |
Digital circuit that squares a 4-bit input A few decades ago, I found a digital circuit that squares a 4-bit input in an old textbook (perhaps 1970s or 1980s). (The figure below is not the original. It differs from the original in that it has been rotated 90 degrees. Also the original figure had an error in the circuit diagram that has been... (more) |
