Punch cards are made thoroughly obsolete many orders of magnitude over by modern storage and IO technologies. What replaced Smith Charts? The >$100k only-a-few-years-old VNAs next room over still plot S11 and S22 on Smith Charts and I'd bet you an entire VNA that this will still be the case in 10 years.
Preemptive: No, 3D Smith Charts do not obsolete Smith Charts, just like 3D line charts don't obsolete 2D line charts.
- kstrauser 7y ago> Punch cards are made thoroughly obsolete many orders of magnitude over by modern storage and IO technologies. You weren't kidding. From https://en.wikipedia.org/wiki/Punched_card_input/output https://en.wikipedia.org/wiki/Punched_card_input/output : > If all columns of an 80 column card encode information this translates to approximately 2,500 characters per second (CPS). According to https://www.techradar.com/reviews/samsung-970-evo-plus https://www.techradar.com/reviews/samsung-970-evo-plus a 970 EVO Plus SSD is about 1,400,000 times faster. Wow. I would love to go back a few years and blow young me's mind.
- Vysero 7y agoWell in my EMAG class in college we were introduced to Smith Charts. We studied them for about a week or two and used software to check our work. So software has replaced them. There is nothing a Smith Chart can do that a simple software application can't manage in 1/16'th the time.
