Analog Specs Just Test Them!
In the beginning– just test the specs.
Analog circuits have been around a long time. Consider a simple LRC circuit– the inputs and outputs are continuous wave forms.
This remains a key differentiator from digital circuits which operate on 1’s and 0’s.
Continuous waveforms require different test equipment and test techniques. Analog circuits have properties of impedance, 3Db points in the frequency domain, transform functions. They can be treated like a lumped circuit or a distributed circuit in which signal integrity and transmission line theory apply.
So testing is easy- you just test the specs. [Read more…]
