Ah, maybe so to you, but it's based on many years experience in a hard place like SE. (more) |

Downvotes are indicators to people seeking help on a particular subject that an answer may not contain useful information and should be ignored. Now, to me, that seems like a good reason to prevent ill-placed downvotes. It's the main reason why I downvoted your answer BTW. (more) |

@#53110 in downvoting this answer you are, in effect, telling the author of the answer that his answer is worth less than no answer at all. I certainly don't think this is the case. Look at it from the perspective of the guy answering; he put some effort in to produce words that maybe could be improv... (more) |

Reasonably competent (and even junior ranking) engineers will certainly understand the term mentioned. I don't understand why you think they won't. (more) |

A: Let's make all downvotes public Very short answer - get rid of downvotes on answers; just don't allow them In fact, wouldn't it be a better policy to award upvotes to people who point out errors. That would encourage folk to want to help people fix crappy answers without the discontent that downvotes bring. OK, it may be a trick... (more) |

@#53110 I choose to complain for sure and, if I'd known about a debate (I received a message just minutes ago from Olin), I'd have both complained and participated. I will of course participate now that I know there's a debate. (more) |

@#36396 I'm up for it. I would also suggest that new users need to reach a certain reputation before they are allowed to downvote thus preventing moron abuse. I might also suggest that anyone downvoting (that can d/v) are given a small list of options to tick for their reasons. OK this last bit may b... (more) |

On this answer I'm still registering 7 downvotes: -

And I'm a volunteer too.
I'm not comparing the scale of this to a criminal offence - it's far less than that but, if a criminal offence "outs" the perpetrator then why shouldn't this lesser offence? (more) |

| Question | — |
Still getting downvotes - what are you guys doing about it? It's still happening: - Image alt text Can someone actually do anything about this? This has happened on stack exchange before but this is ridiculously more far fetched than what has ever happened there. Do you really want to be tarred with the same brush? If this were a criminal offence ... (more) |

A: Flyback transformer for Vout > Vin > How is it possible to generate 500V on a trafo secondary given the 1:1 ratio? In a DCM flyback transformer circuit, the secondary winding is being used as a pure inductor. So, once the primary is disconnected, the rate at which the core magnetic field collapses, dictates the secondary termina... (more) |

Then this site should prevent users who wish to remain anonymous from casting downvotes on anything. Personally I would choose not to be anonymous as I believe in openness in things like this. If you wish to avoid looking like big-brother stack exchange then you should consider this. (more) |

Just tell me the name of the downvoter and there's a chance I might be able to give you the reasons they downvoted. It's probably some revenge thing from stack exchange. (more) |

| Question | — |
Why am I receiving so many downvotes at once? Why am I getting these downvotes? It started last week (or the week before) and now it seems like it's getting contagious: - Screenshot of 9 downvotes on February 6, 2022 Seems like this site has some of the same outrageous inclinations as stack exchange. Downvotes should be registered and view... (more) |

@olin - keep them ready and warmed-up for the next bad post. In case anyone thinks Olin is being harsh, he's not. A little bite at a person's ankles to remind them what is expected of a good question isn't being unnecessarily rude; engineering requires absolute attention to detail if you are to be go... (more) |

A: How to protect RF switches from ESD? Currently there are $\boxed{\color{red}{\text{three}}}$ downvotes so maybe someone can explain why this has happened. Anyway, on to my downvoted answer: - You have "mentioned" the threat (the ESD level) but, you haven't defined the peak voltage or current limit for the potential victim. Neither ha... (more) |

Basically, if you look carefully and read between the lines of what Olin wrote, he is saying the following:
**look in the RFIC datasheet**. Can you remember my comment from under your question: *Don't you need to give details for the RFIC device since The RFIC manufacturer recommends to "add filteri... (more) |

AGC (the variable gain amplifier) is best placed on the front-end before the mixer. However, the control voltage for it can come from after the demodulator or the IF stage. For FSK, it's likely that all you will have is a limiter-circuit that runs balls-out because, well, that's what FM requires i.e.... (more) |

The LNA appears to be the one that is adjusted and, that makes a lot of sense because that's where you'd want it to be to maximize noise performance i.e. you'd want the LNA to have variable gain to give the AGCed signal a better SNR. (more) |

Why does your diagram have time accumulating from right to left. This is very unconventional and I would be cautious about posting a picture that shows it like this. Maybe it came from a web site that's a little flaky?
You said this: `Assume now that the bandwidth of the signal is 2kHz.If the band... (more) |
