Terminator 3, Terminator Trio

[Toros]

Maybe the creator had a huge surplus of these chips leftover from Soviet era and decided to make good use of them.

Yes that is right. The author himself acknowledges it.

[dbanner]

It was just a guess. Well done to the creator of terminator design.
Now I will have a go at making this project, curious to see for myself the performance.

But first, I must read thoroughly the various threads on Ru forums to get a feel for it. This is wise approach.

Here it is written clearly about the problem of CMOS as an amplifier. I have nothing more to say. CMOS gate as linear amplifier - Microcontroller Group, Moorabbin, Melbourne , AN-88 CMOS Linear Applications - AN-88.pdf ,Линейный усилитель на КМОП - транзасторах | Контент-платформа Pandia.ru

The information is too much to be able to translate it from Russian.
Below I give you a very detailed instruction for Terminator setup. It is in Russian, but the text part with copy-paste can be translated into a Google translator.
The scheme is not exactly what you liked (from KT315), but the main part of the detector is the same.

Thanks SCS, I think I understand now a little better. I am student of electronics and still learning. Your two tone discrimator circuit I will build first.

[dbanner]

Toros, many thanks. I will have a look.

[scs]

If you want to do something good do a classic 3.You can do another one channel for two-tone discrimination.

[tonemgub]

can I put cd4069ube or must it be hef4069ubp?

[DeD.]

Only use HEF4069

[tonemgub]

but in my country only have hef4069ube not ubp
