[Alan’s] friend came to him with a problem. He loved listening to his scanner, but hated the volume differences between stations. Some transmitters would be very low volume, others would nearly blow ...

In last month’s column [“Automatic Pumpdown Systems,” Nov. 5], we talked in general about the automatic pumpdown cycle and why it is the only sure remedy for refrigerant migration to a compressor ...

Variable gain amplifiers often use a mechanical potentiometer to set the gain. An example is a volume control dial. However, when the analog signal path is digitally controlled, a digital ...

NOJA Power has released Relay Firmware 1.16, the latest version of its firmware platform for OSM series automatic circuit reclosers. With the release of Firmware 1.16, NOJA Power has included major ...

To help achieve more precise control of gene therapy, engineers have designed a new control circuit that can keep gene expression levels within a target range. The method could be used to deliver ...
