Noninteger delay Sampling

$x[n]$ → $D/C$ → $x_c(t)$ → $h_c(t), H_c(j\Omega)$ → $y_c(t)$ → $C/D$ → $y[n]$

1. restore continuous

2. resample

$D/C$ converter

Non-integer delay $\Delta$ and $H(e^{j\omega})= e^{-j\omega \Delta}$

• integer case is $y[n] = x[n- \Delta]$

• non-integer case $y_c(t) = x_c(t - \Delta)$
