Square-wave modulator has variable frequency and pulse width

A few years ago, I worked at a disk-drive company. We had a plating facility that required square waves to drive the high-voltage plating operation. The challenge was that the square wave’s pulse width had to be variable, along with the duty cycle. Also, ... EDN Asia

Power relays give designers much to ponder

My first experience with a relay came about when a friend found a radiosonde – a small balloon-borne weather instrument – in the woods behind his house. My friend Ben wanted the parachute, so I got the electronics. As a kid of 11 or 12, the circuitry ... ECN Asia
