Logic testers are simple but very helpful devices ... When the tested point is above 2 volts, the D4 LED lights up signalling a logical “1” state. Another plus of the featured circuit is the fact that ...

Logic probes are simple but handy tools that can be had for a couple of bucks. They may not be the sexiest pieces of test gear ... logic probe is based on a circuit by [Tony van Roon].

Using a simple circuit ... output. A logic zero on the cathode node lights the LED, and a logic one turns it off. The cathode signal is the inverted form of the PWM output. In this example, the PWM is ...

It may be possible to reach new levels of miniaturization, speed, and data processing with optical quantum computers, which use light to carry ... a prototype for a logic circuit with two ...

The first integrated optical quantum logic circuits are a step in the right direction. Quite generally, the promise of quantum computing lies in making use of the 'parallelism' and 'connectedness ...

Why it matters: For decades, scientists have dreamed of building computer chips that use light instead ... of performing simple logic operations entirely with light. Logic gates are the building ...

In fact, there aren’t any logic ... circuits found in a 1967 book Electronic Counting Circuits by J.B. Dance. The theory of these circuits rely on the different voltages required to light ...
