upsampling and adding delay to a sequence

5 views (last 30 days)
Hi
I have a simple query.
Suppose i have a signal s = randn(1,10), if I want to add delay 100ms to this signal, what should i do?
I heard about upsampling the signal and then adding zeros, but can you help me with an example code
s = randn(1,8);
delay = 100ms;
s1 = upsample(s,?);
s_delay = [how many zeros, s1]?
Is that approach right?

It is not possible to add a delay to a signal unless you know what the sampling frequency is.

Looks plausible to within my limited filter knowledge.

Hi again, Morning!
Just realized that we may use the translation property of Fourier transform, but unable to figure out how.
if h(x) = ƒ(x − x0), then  H(w)= e^{-2 π i x0 ω }F(ω)
Can you help me with this approach?
Cheers
