(2125/2295 Hz)
Generate white and pink
noise
Generate arbitrary
waveform
Special PC program
allows to design custom waveforms and upload the generator memory
PIC18F4550 based Audio Generator project implements a Digital
Direct Synthesizer (DDS), a type of frequency synthesizer used for
creating arbitrary waveforms from a single, fixed-frequency reference
clock.
In its simplest form this particular circuit
configuration can be implemented from a precision clock reference, an
address counter, a programmable memory, and a D/A converter
