This simple circuit tests speakers, microphones, transformers and voltage. It’s basically a very low frequency oscillator that produces extremely short ‘fruity’ pulses. The type of sound produced is ...

When first learning about and building electronic circuits, the first things all of us come across are passive components such as resistors, capacitors, and inductors. These have easily-understandable ...

PinPoint 3-PXIe offers component-level diagnostics and high-performance functional testing in one system. Astronics released its next-generation circuit card diagnostic and test system, the PinPoint 3 ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

While this sub-$20 board may not gain pride of place in your T&M rack, it's a fine tool for hobbyist and pro alike, and demonstrates the power of clever design. Recently, while thumbing through eBay, ...

The supply voltage is shared between components in a series circuit, so the sum of the voltages across all of the components in a series circuit is equal to the supply voltage, \({V_s}\). if two ...
