Deoxit is a unique electrical contact cleaning. Not only does it break up surface-level oxidation and flush it away, but it also protects against future oxidation! There...
Slew rate shows how fast an operational amplifier can respond to an input signal’s change. The “slew rate limit” is an important consideration. However, when looking...
Like any versatile tool, there are tons of options when looking at DMM models. Learn what various features mean so you can decide on your own what DMM capabilities you...
Creating a bode plot from a simulation (or transfer function) is easy. But what if you want to create a bode plot for a REAL op-amp circuit or filter? One way is to measure...
