In isolation applications, such as situations where one needs to transmit signals despite the presence of high voltages, reject excessive noise, and eliminate ground loops, optocouplers and pulse transformers are commonly employed. Optocouplers use optical coupling while pulse transformers use magnetic coupling. However, designing pulse transformers is considerably more challenging compared to optocouplers. The load…

Can telephone lines have a significant impact on the future? Can twisted copper wires transmit Internet data securely, reliably, and at high speed to enable viewing of high-quality moving images, sound, and large amounts of data on personal computers or televisions? The answer is yes, as proven by the increasing success of DSL (digital subscriber…
