What You Can Learn From a Frequency Sweep Test？

With a frequency sweep, you can extract the bandwidth of a circuit or system, and you can generate a transfer function.

Nonlinear circuits require more sophisticated simulations, or they require complex iteration in the time-domain.

What You Can Learn From a Frequency Sweep Test

Frequency sweeps are only defined for linear time-invariant circuits.

With a frequency sweep, you can extract the bandwidth of a circuit or system, and you can generate a transfer function.

Nonlinear circuits require more sophisticated simulations, or they require complex iteration in the time-domain.

Poles and zeros for a circuit can be determined from a frequency sweep test.

Time-domain and frequency-domain simulations are the two fundamental tools for examining the behavior of your electronics. As their names suggest, time-domain analysis is all about examining what happens to a specific signal over time, regardless of its bandwidth. This gives you a comprehensive view of circuit behavior in the time domain, and you’ll have an opportunity to quantify things like signal distortion and attenuation, simply by comparing input and output signals.

Analog engineers generally work in the frequency domain. The goal in designing analog electronics is to manipulate different frequencies with your circuits, and the fundamental tool used in these simulations is a frequency sweep test. When you have access to a powerful electronics simulator with verified component models, you can examine how your system responds to different frequencies.
