Logic testers are simple but very helpful devices in testing digital circuits. A logic probe can be designed in many different ways. In this particular design, a combination of discrete and TTL logic ...

The circuits successfully performed the sum-of-product operation at 2.8 kHz. The full potential of memristors was demonstrated when the devices were made to actively re-program themselves.

Measurement instruments mustnot affect the circuits they’remeasuring. A logic probe, for example,must correctly detect logic levels, and itmust place no undue loads on the testcircuit. The logic probe ...
