DELAY_f

Discrete time delay

Block Screenshot

Description

This compiled super-block implements a discretized delay. It is built with a shift register and a clock. The value of the delay is given by the discretization time step multiplied by the number-1 of state of the register.

\left\{
    \begin{array}{l l}
        T_0=length(Register)                                                  \\
        y(t) = Register(n)      & \text{when}\ t < nT_0                     \\
        y(t) = x(n*(T - T_0))   & \text{when}\ t\in[n;n+1]*(T - T_0)
    \end{array}
\right.

.
