ep-4yy13 DSP – week 6
Stop the experimental music
(click the picture)
DSP – according to the Arctic Monkeys…
The time domain:
The frequency domain:
Samples, impulses, and convolution
(in the time domain)
- Decomposition
- Unit impulse (delta function)
- convolution (from the input side and output side)
- filters

Destroying information
Abstract is what remains after shedding details.

Assignment:
See notes from last week. https://reactivemusic.net/?p=10059
Work through the convolution examples on your own. Its important to have a physical concept of signals, in various transformations. Become a wave. Have an out of body experience. Take a good look at yourself.

Proof of concept
The next step will be to clean up the external so it allows mode, frequency, gain setting – and doesn’t break.
