How do you generate delay simply by dropping or repeating samples?

I don't know whether this is a trivial question or not but I couldn't get it.

I was reading about delaying a signal after it is digitized. For what I read-

1) If you want to increase the delay, repeat the samples. How can this increase the delay???
2) If you want to decrease the delay, drop the samples. I don't fully agree with this. Confusing....


I would be happy if you could clear me this doubt.

Thanks a lot

if it is about taking multiple samples and averaging the result or considerily only the last sample, it's true as it takes certain amount of time to take one sample. Taking multiple samples will add up to delay equel to multiple of one sample delay.
