You have designed an op-amp circuit to measure a small voltage. The circuit gain is -10V/V, but it appears that the input impedance to the circuit is effecting the device as it is being measured. How ...

In the “Say It with Me” series, we’ll take a commonly used concept out of electronics and explain it the best we can. If there’s something that’s been bugging you, or a certain term or concept that ...

Most analog folks are familiar with the use of a pulse generator and a scope to measure cable reflections and impedance. For those who are not, this lashup is called a reflectometer. Available as ...
