![]() It is useful in checking that filters are behaving as expected, or that amplifier stages will work correctly across the required frequency range.įrequency graphs can also be used to plot small signal input and output impedance against frequency. As well as the magnitude, however, the phase of the probed signal can also be seen.įrequency analysis produces frequency response or Bode plots. Instead, the simulation is similar in effect to connecting a frequency generator to the input, and looking at the output with an AC voltmeter. Only one frequency is considered at a time, so the plots are not like those seen on a spectrum analyser, where all frequencies are considered together. ![]() ![]() The Frequency graph allows you to see how the circuit behaves at different frequencies. ![]()
