Before revision: Oscillators|A series of mixed vertical oscillators response spectrum|A plot of the peak acceleration for the mixed vertical oscillators A response spectrum is simply a plot of the peak or steady-state response (displacement, velocity or acceleration) of a series of oscillators of varying natural frequency, that are forced into motion by the same base vibration or shock.
