WebThe DDS architecture exploits the symmetrical nature of a sine wave and utilizes mapping logic to synthesize a complete sine wave from one-quarter-cycle of data from the phase accumulator. The phase-to- amplitude lookup table generates the remaining data by reading forward then back through the lookup table. This is shown pictorially in Figure 5.

WebOn each look-up the index to the look-up table is incremented so that new values can be loaded. The value from the sine table is written to OCR0A. In this way the pulse width is modulated to the sine wave. Note that the OCR0A register is buffered and that the latching of the buffer into the actual OCR0A WebThe sawtooth wave (or saw wave) is a kind of non-sinusoidal waveform. The convention is that a sawtooth wave ramps upward and then sharply drops. However, in a "reverse (or … WebOne way to reduce the truncation in the address lookup is to have several smaller lookup tables in parallel and use the upper bits to index into the tables and the lower bits to weigh them for linear or quadratic interpolation. Ie use a 24-bit phase accumulator to look up into two 16-bit LUTS. Address into the truncated 16 MSBs, and that plus 1. rowling purse

WebJul 20, 2024 · Originally, we used band-limited Sawtooth waveforms but Szabo advises against this in his analysis. As such, we have now implemented his recommended strategy by using a pitch tracked high pass filter and standard Sawtooth lookup tables. This strategy should bring our emulation closer to the original Super-Saw.
