hex to bin file conversion in bash

This question has already been asked in many different forms. I need to convert a file that looks like this

41 20 42 20 43 20 44

to this

A B C D

This is just an example, but files WILL certainly contain non-printable characters. I wrote a simple piece of code in C that does this, but I'm curious can it be done with some of the basic tools that are available on most Linux distributions, such as dd or tr, or maybe some clever bash script?

For the sample input this works (in bash at least). Whether it will work for all input I'm not sure but I expect it probably will.

printf %b $(printf '\\x%s ' $(< infile)); echo
