A mathematical model of a microwave acoustic delay line is derived and presented which takes into account the mechanical resonances of a finite acoustic delay medium. A computer simulation of the model shows that when the delay medium is taken to be finite the frequency response of the delay line is different from the response of a delay line with a completely absorbing infinite delay medium. This difference in response is obtained experimentally when changing from pulse operation to continuous wave CW operation of a delay line. This is the first model known to the author which demonstrates this effect.
