Frequency response plot.

The frequency response is the plot at the bottom where the frequency points are color-coded. You can use the slider on the frequency response plot to interactively explore the time response and the FFT at each frequency of the input. In the time response plot, the steady state portion of the output signal is the thick line.A Bode plot maps the frequency response of the system through two graphs – the Bode magnitude plot (expressing the magnitude in decibels) and the Bode phase plot (expressing the phase shift in degrees). Bode plots were first introduced in the 1930s by Hendrik Wade Bode while he was working at Bell Labs in the United States.The response amplitude is then plotted against the excitation frequency which presents the frequency response of the oscillator displacement versus the excitation frequency. The frequency response amplitude frequency curve can also be obtained from plotting the modulus of Eq.
