Question
For TTL IC, what are the voltage levels at which Logic 1 and Logic 0 will be detected? Is there a gap between these logic levels? If yes, why? computersagar (talk) 12:19, 30 January 2012 (UTC)


 * I believe this is covered by Logic level which is clearly linked from Digital_signal. ~Kvng (talk) 15:53, 19 January 2020 (UTC)

Schizoid article
This article seems to have failed to define what it's talking about. The clock waveform as digital signal is a completely different meaning of digital signal than the one in the lead. We could probably fix it to cover both, but right now it's just unclear what the article is about, and there's very little there anyway. In spite of the above-referenced archived discussion, nothing was resolved about what the topic of this article is. It could become a disambig to reference discrete signal and digital or something like that, or it could be that digital waveforms such as clocks and data are the intended topic. I might try a stab at it and see where it takes us. Dicklyon 19:24, 8 September 2006 (UTC)


 * I believe this concern has been addressed somewhere in the 12 years since you posted this. ~Kvng (talk) 15:55, 19 January 2020 (UTC)


 * In general - 'signal' means flagging or symbolism that represents information - whether it be a 'yes' or 'no' information, or some other information. I agree - a clock 'waveform' is just a waveform, unless we purposely want to use it to convey information, such as timing information - such as providing a signal to tell the receiving side when to do something, or when it is ok to do something. Also - the article attempts to define 'digital signal'. However, an 'analog waveform', such as a sinusoid can fit the description of a 'digital signal' - such as if the frequency of the sinusoid is f1 for some amount of time, and f2 for another amount of time, then there's digital information being sent using analog waveforms. So here, analog signals (which are also analog waveforms) being used to send digital information - is like a case of digital signalling using analog 'signals'.

CodSim link
''Originally posted to my talk page. I'm copying it here for any necessary discussion. This is the revert in question.'' ~Kvng (talk) 14:24, 3 May 2021 (UTC)

I'd like you to review your undo at my contribution in the Digital_signal article as "not closely related". I'm associated professor at the University of Malaga and I have taught Digital Data Communication over 15 years, including the OSI physical level and extensively explaining the use of Digital Signals and Digital Analog Modulations and every perturbation caused by the medium. The simulator that I linked to the page was written precisely to allow students to understand and experiment by themselves with coding of messages using digital signals and analog modulations. If you review the simulator, you will see that each exact topic of the article is reflected there as it was written following the contents the university level course on data codification.

Also, any suspicion about spamming can be discarded, as the simulator was written as a free HTML tool with an Creative Commons License (Attribution-NonCommercial-ShareAlike) as my intention is that it can be used in Universities and Schools with minimum resources to teach technology. I think it is closely in synchrony with the spirit of Wikipedia.

I'd appreciate if you restored my edit as I'd like not to start a ping-pong of undo and reverts. Best regards, G-DACUMA (talk) 13:45, 3 May 2021 (UTC)


 * I have restored the link. ~Kvng (talk) 14:24, 3 May 2021 (UTC)

Proposed merge of Digital signal (signal processing) into Digital signal
the distinction is already noted in Digital signal fgnievinski (talk) 19:17, 20 February 2022 (UTC)


 * Oppose - Digital signal is covering three types of digital signal in WP:SUMMARY style. While there aren't stand-alone articles for the other two types, merging Digital signal (signal processing) here would create an WP:UNDUE issue. ~Kvng (talk) 14:29, 23 February 2022 (UTC)
 * Closing, with no mergegiven the uncontested objection with no support and stale discussion. Klbrain (talk) 18:46, 23 August 2022 (UTC)
