A simple electric circuit learns to classify data in a creative new design that could lead to more energy-efficient machine-learning hardware.

However, for some loads, even this circuit might be an improvement over a simple resistor. Suppose you had a black box instead of an LED.

Coming from an IT background to an AM transmitter site might leave you with a world of questions. Mark Persons explains the ...

Figure 5. The detection impedance resistor (R51) of a simple, Class 0, PD interface circuit Classification : How much power will you be needing? During the classification phase, the PSE uses the ...

The circuit above uses an R-2R resistor network – often called a resistor ladder – which you can learn much more about from the reference page that [Collin] links to.

A simple circuit uses one control device to control bass and treble simultaneously, with a symmetric response that is flat at the center of the adjustment range.

Parsing various resistor band colors is fairly simple once you know what each color means. Orient the resistor with the gold or silver band on the far right.

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India ...

This simple circuit measures the strength of a radiated signal from a transmitter. It is commonly used by model airplane builders to check whether their transmitter are really transmitting the radio ...

A Simple Over-Voltage Protection Circuit for LED Drivers This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V ...
