Ausias Garrigós and José M Blanes EDN Designers use electronic dc loads for testing power supplies and sources, such as solar arrays or batteries, but commercial ones are often expensive. By using a power MOSFET in its linear region, ...
Tamara Papalias EDN Comprising four twisted pairs within a durable external sheath, Category 5 network cable offers a common and cost-effective choice for transmitting component-video signals. Three of the pairs can carry RGB video signals, and the ...
Don Sherman, Maxim Integrated Products EDN With the aid of a simple mounting system and some soldered-on weights, a piezoelectric “bender” can detect mechanical shocks. The bender comprises a piezoelectric-ceramic element bonded to a ...
Bjoy Santos EDN Regardless of its color, an LED's light output varies as a function of forward current and ambient temperature. As Figure 1 shows, an LED's light output can vary by as much as 150% over its operating-current range. In response, a ...
