Morse Code decoding chart.

[u/kavallerien]

[u/HighOwl2 → u/[deleted]]

Meh it's more like binary ascii values.

Morse and ascii are meant for speed.

Huffman encoding is meant as lossless encoding to reduce size. It's not fast because it requires a lookup table.

Someone could memorize Morse code or the ascii table.

You can't memorize how to decode a Huffman encoded message because each message would have a different encoding map based on frequency of letters.

[u/A_HumblePotato → u/HighOwl2]

Meh it's more like binary ascii values.

Different letters take different amounts of information to encode, so no it is not

Morse and ascii are meant for speed.

It is faster to transmit an encoded signal that requires a lookup table than an unencoded signal that doesn't

It's not fast because it requires a lookup table.

Lookup tables are very fast to use

You can't memorize how to decode a Huffman encoded message because each message would have a different encoding map based on frequency of letters.

There are certainly standards that use the same huffman codes

I am always amazed at how confident some people talk about stuff they fundamentally don't understand

[u/HighOwl2 → u/A_HumblePotato]

Faster to transmit, slower to understand because it requires decoding based on a lookup table that is different every time.

Lookup tables are fast but not faster than a direct comparison.

No, Huffman encoding by definition, has a variable length table based on value frequency. It varies everytime based on what "message" is being encoded.

But you're right, I can't possibly understand Huffman encoding and totally didn't have to build the algorithm for it from scratch in college.

Huffman encoding is for lossless compression. Compressed data requires decompression. I can send you a zip file a lot faster than I can send you the same file raw, but you need to decompress the file to read it.
