Reed responses

Frequency and impulse responses of the discrete system show that significant physical parameters ( $\omega_r, g_r, k_r$ ) are well preserved.

Responses obtained with

$\omega_r=23.25\cdot 10^3$ [rad/s].
[Hz]
$k_r=1.25 \cdot 10^7$ [Pa/m]
$F_s=22.05, \ 44.1, \ 96$ [kHz]

Solid line: continuous response
Dashed line: 1-step Weighted Sample method
Dotted line: Backward Euler method
