Abstract:
This paper describes a prototype design
to demonstrate the design of arbitrary waveform
generator based on Direct Digital Synthesis
(DDS) technique implemented on Digital Signal
Processor. The key idea is the utilization of Look-
up Table (LUT) supported with Code Composer
Studio (CCS) platform. The arbitrary waveform is
synthesized by storing samples in the memory of
TMS320VC5416 Digital Signal Processor (DSP)
in LUT form. The processor while executing the
program recalls the stored samples sequentially
and presents them to the Digital-to-Analog (D/A)
Converter and the D/A converter generates the
desired arbitrary waveform. The experimental
results have been included.
