Apply square waves to simplify measuring frequency response Engineers perform the majority of tests on electronic circuits in the time domain. Because many frequency-domain measurements require dedicated network analyzers, engineers sometimes fail to perform needed tests. However, when working with analog circuits, you can often make frequency-response measurements without a network analyzer; your existing time-domain instruments (for example, a digital oscilloscope) can extract the frequency-response information. The only requirement on the instruments is that they be able to send time-domain measurements in digital form to a computer. Digital oscilloscopes are ideally ...
