Abstract :
A surface-acoustic-wave comb spectrum oscillator (SAWCSO) for sensor applications employing a long delay line is described. It generates low jitter narrow pulses in the kHz range. The relative sensitivity to velocity changes is close to the theoretical maximum and at least twice as high as in single mode oscillators.<>
