AN INTRODUCTION TO THE SHOCK RESPONSE SPECTRUM
INTRODUCTION Spacecraft and launch vehicle components encounter mechanical shock from a variety of ... 1 There is an equivalency between the convolution integral and the multiplication of Fourier transforms. Thus, the calculation process can be carried out in terms of Fourier transforms. This

www.vibrationdata.comPIANO KEYBOARD The number beside each key is the fundamental frequency in units of cycles per seconds, or Hertz. OCTAVES For example, the A4 key has a frequency of 440 Hz. Note that A5 has a frequency of 880 Hz. The A5 key is thus one octave higher than A4 since it has twice the frequency.
