10. Adding Band-Limited Step Differences | Home | Next |
By working with a buffer of differences, band-limited steps can be added easily. As the step is sampled, the difference from the previous sample is added to the buffer of differences. When the final samples are needed, a running sum is applied to the buffer to yield absolute samples:
