# #14. Demodulate¶

Note

Following documentation is a cooperative result combined from our Discord chat and numerous pull requests. Thanks to everyone who helped!

## Image¶

This image was produced from the fourteenth radio transmission using previously contributed code.

This partly annotated version of the image was made using code from message #3.

## Interpretation¶

This appears to define an inverse operator to that from #13. Modulate, demonstrating that :341 (dem) is the inverse of :170 (mod), and vice versa. This suggests that :341, when applied to a linear-encoded number, will create a grid-encoded number.

The behaviour of mod when applied to a linear number, or dem when applied to a grid number, is not defined.

## Decoded¶

dem
ap dem ap mod x0   =   x0
ap mod ap dem x0   =   x0


## Code¶

The Haskell code has been revised to decode new glyphs.
