Let's talk about advanced synthesis techniques. Specifically, the synthesis of classic waveforms that are so straightforward to realize with simple analog circuits, can lead to serious headaches in the digital domain.

The main idea is pretty simple. We can generate a simple sawtooth by integrating a unit impulse minus some DC offset. The problem is that the unit impulse itself contains all frequencies per definition, so integrating it will also lead to an infinite number of partials.

The idea behind the BLIT is: if we bandlimit the impulse, we‘ll have a method to generate a bandlimited sawtooth.
