Reconstructing a signal from its samples using Interpolation
We have learned in class that a signal can be reformed by obtaining multiple samples of its signal and using an important procedure we know as interpolation we can obtain the original signal of the function.
- it is noted that if the sampling instants are sufficiently close, then the signal can be reconstructed using a lowpass filter. the output is then considered to be:
$ xr(t)= xp(t) * h(t) $
or with xp(t):
$ xr(t)= /sum{n=-/inf}{/inf} $
