Actually this isn't really an upgrade question, but it is like one...<BR> <BR>I have ordered a few barebone Ipaq desktops and I planning to use parts I have on hand (CPU, RAM, HD...) to get them up ...

Analog topologies abound for converting current to voltage, voltage to current, voltage to frequency, and frequency to voltage, among other conversions. Figure 1 joins the flock while singing a ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

The Model 1761 triple-output digital dc power supply uses a standard 115-V ac outlet as its power source. This benchtop unit provides two variable voltage outputs of 0.0 to 35.0 V dc and 0.0 to 3.0 A, ...

For more than a century, scientists have relied on separate tools to measure the three core building blocks of electricity: volts, ohms, and amps. Each describes a different piece of how electricity ...
