Amplifying the small signals produced by sensors in a low-noise circuit is a very common but difficult problem. Designers will often use an operational amplifier (op amp) with bipolar inputs to ...

This Design Brief introduces a computationally efficient network that computes the derivative of a discrete time-domain (digital) sequence. While recursive differentiating networks exist, this article ...

Machines need sensors and transmitters to operate reliably and consistently. All it takes is a small drop in air pressure or a slight jam to cause a machine to crash; these sorts of problems can often ...
