subtle differences in the sine-wave lookup table and envelope generator to YM3812 (e.g. the modulator waveform on YM3812 is delayed by one sample, whereas both carrier and modulator waveforms on OPL3 are properly synchronized) [3] The YMF262's FM synthesis mode can be configured in different ways: [5]: 27.16–27.18 [8]
The term "waveform table" (or "wave shape table" as equivalent) is often abbreviated to "wavetable", [14] and its derived term "wavetable oscillator" [15] seems to be almost the same as "table-lookup oscillator" mentioned above, although the word "wave" (or "waveform", "wave shape") may possibly imply a nuance of single-cycle waveform.
One 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.
When the program requires the sine of a value, it can use the lookup table to retrieve the closest sine value from a memory address, and may also interpolate to the sine of the desired value, instead of calculating by mathematical formula. Lookup tables can thus used by mathematics coprocessors in computer systems.
In electrical engineering, a function generator is usually a piece of electronic test equipment or software used to generate different types of electrical waveforms over a wide range of frequencies. Some of the most common waveforms produced by the function generator are the sine wave, square wave, triangular wave and sawtooth shapes.
Schematic diagram of additive synthesis. The inputs to the oscillators are frequencies and amplitudes .. Harmonic additive synthesis is closely related to the concept of a Fourier series which is a way of expressing a periodic function as the sum of sinusoidal functions with frequencies equal to integer multiples of a common fundamental frequency.
A DDS function generator. Direct digital synthesis ( DDS ) is a method employed by frequency synthesizers used for creating arbitrary waveforms from a single, fixed-frequency reference clock. DDS is used in applications such as signal generation , local oscillators in communication systems, function generators , mixers, modulators , [ 1 ] sound ...
Intersil ICL8038 ICL8038 operation (simplified; sine wave is derived from the triangular wave). The ICL8038 waveform generator was an Integrated circuit by Intersil designed to generate sine, square and triangular waveforms, [1] based on bipolar monolithic technology involving Schottky barrier diodes.
