In the nearly 40 years since electronic control systems first became common features of industrial machines, controls theory has necessarily evolved to keep pace with machine design. Early on, systems ...

The brain is key to our existence, but there’s a long way to go before neuroscience can truly capture its staggering capacity. For now though, our Brain Control series explores what we do know about ...

Linear regulators use an internal transistor to control the output voltage. That transistor needs some headroom—you can’t get 5-V output with a 5.01-V input. That headroom is also called dropout.
