Various things are still missing. All the answers to https://electrical.codidact.com/questions/279585 is one obvious example. Note that the question list says "3 answers" (which seems correct from memory), but there are none in the question itself. (more) |

A: What is the difference between differential amplifier and differentiator? A differential amplifier and a differentiator are two completely different circuit blocks. Differential Amplifier A differential amplifier has two inputs and one output. It takes the difference between the two inputs, multiplies that by the gain, and makes it the output. Out =... (more) |

A: Are questions about proper cable repair on-topic? Lundin's answer notes: I just realized that the on-topic page https://electrical.codidact.com/help/topics doesn't address electronics assembly. It does now. I just added: Physical construction of circuits or electrical products, within limits. This is generally on topic when there is some e... (more) |

A: Bit-rate vs Baud-rate Baud rate is about the speed of bit slots in the channel or symbols. Bit rate is the rate at which actual data is transmitted. Put another way, baud rate is what you see when you look at a scope trace of a communication signal. Bit rate is how fast data gets from one end to the other. The bit... (more) |

Good circuit, +1. However, I'd break the pot up into a fixed resistor for the top part, and a pot to only allow up to a volt or so max for the bottom part. That reduces the settings that might cause damage, in addition to giving you higher adjustment resolution. With 100 kOhm fixed and a 10 kOhm p... (more) |

**Question cleaned up, and comments that became a discussion deleted**. tlfong01, don't get used to others cleaning up your questions for you. This site is for questions and answers, not long winded side stories or discussions. Let this be an example of how you should have asked. Others, if you ha... (more) |

A: How to plot the I-V curve of a tunnel diode? Apparently you want to measure the current/voltage relationship of a tunnel diode. The tricky part is that the voltage isn't unique for currents over parts of the range. From your question: Image Note that the current is still unique as a function of voltage. One solution is therefore to swe... (more) |

A: Creating an additional "user" Personally I'd rather have everyone use their real name and affiliation. That basically puts their reputation out there on anything they say. If you really believe in something, have the guts to say so. If you don't, then I don't want to hear it. However, that's not the policy of the site. I w... (more) |

@Lundin: Feedback needs to be public so that everyone can see what the norms are, and that they are applied fairly. I certainly don't want to explain why 20 similar post are too broad, when doing it only a few times may head off the others. If you can't handle being publicly criticized, then you do... (more) |

What you call "confrontal" is bluntness, and somewhat deliberate. Experience elsewhere has shown that subtlety is merely an invitation to ignore the content. (more) |

One thing that helps to address this issue is to have reasonably good explanations of why the question was closed. In the particular case cited, I think the close text explains the situation reasonably well. If users genuinely want to understand what is wrong with their question, they will find sup... (more) |

A: Please find other ways to hide inloved questions that prompt close I have boycotted the SE and neither asked or answered any questions so am happy to have a new home here. I'm glad you're here. You might also want to mention this in your SE profile, and point people here. For example, see my profile on SE. Also I believe that my and many others who have call... (more) |

| Answer | — |
A: Using FET based followers and design rules FET source-followers are generally less predictable than BJT (bipolar junction transistor, like NPN or PNP) emitter-followers. An emitter follower output is one diode drop below the input. The voltage across a diode varies little as a function of the current, so this offset remains fairly constan... (more) |

@Circ: No, a little positive feedback doesn't make it a latch. It adds hysteresis. The more positive feedback you add, the larger the hysteresis interval. (more) |

All your schematics except Fig 7 are basically unreadable again. You seem to think all those lines "show" things, but they really clutter up the drawing and make it hard to see the circuit under all that mess. (more) |

@Circ: No, what he "invented" was just a comparator with a lot more parts than necessary. (more) |

A: ESD Protection - Differential Amplifier Not a diff amp Something doesn't make sense here. You want A1A to act as a differential amplifier, but that's not how you wired it: Image Here is a real diff amp: Image Note how the right side of R1 is tied to ground, not the opamp output. The diff amp above is really a 3-input cir... (more) |

@Lundin: How a question is worded and what exactly it is asking significantly influences whether answers will be opinions. A good question that someone answers with opinion isn't necessarily the fault of the question, but we want to avoid questions that basically solicit opinions and speculation. (more) |

A: Are questions about electronics market trends on-topic? It could be OK if you are asking about technology reasons why a class of products will be phased out. Asking about forces that cause similar things in the past should be OK too, as long as the reasons can really be known. For example, asking why transistors replaced tubes is fine since good techn...

A: Why is the ACK (acknowledge bit) in the CAN bus frames dominant? What could have been the rationale behind that design decision? In addition to what Lundin said, making ACK dominant means that something out there is actively responding, and that response is affirmative. If ACK were recessive, then the transmitting node being totally cut off from everything else would appear like no error. Put another way, without an active... (more) |

A: Microwave oven interfering with WiFi on the 2.4GHz band Microwave ovens work on the frequency they do because that's one of the main resonant frequencies of water molecules. The radiation excites water molecules, which then transfer some of their extra energy to other surrounding molecules. No, microwave ovens are not intentional radiators, at least n... (more) |
