To perform accurate numerical simulations of the traveling-wave tube in timedomain, a new approach using field decomposition with large reduction ofdegrees-of-freedom has been proposed: the discrete model. To assess itsvalidity, we compare it with the well-established Pierce equivalent circuitmodel in small signal regime. We also discuss associated beam, circuit-beam,and circuit impedances. We demonstrate analytically and with a numericalexample that the newly developed discrete model is very close to the Piercemodel. Interestingly, small deviations do exist at the edges of theamplification band. We speculate that the deviation from reality is on thePierce model side, while the discrete model would be more accurate.
