top secret 1942 ADC Reconstruction in IEEE SPECTRUM

[Jonpaul]

Bonjour à tous, voilà !

My article on IEEE SPECTRUM was a reconstruction of the very first analog to digital converter in 1942 used in SIGSALY Quantizer, part of the top secret unbreakable speech scrambling system.

I am interested in the forum feedback and interest.

I hope you will make a second attempt to demonstrate that ADC at a meeting of the Swiss AES section, once this stupid disease is over.
