Q: If you have to chose an opamp chip,..how do you choose between ttl and cmos?
A: You wouldn't consider an op-amp as either TTL or CMOS. Instead, look at the characteristics you need, such as bandwidth, noise, etc. I bet Analog Devices, Linear Technology, Microchip, and Texas Instruments have op-amp selection guides and application notes. See also, "Op Amp Application Handbook," from Newnes-Elsevier (publisher). ISBN: 978-0-7506-7844-5.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
