Waveform Generation Using TMS320C6745 DSP
This document discusses the generation of different types of waveforms using a TMS320C6745 DSP. It provides programs to generate sine waves, square waves, triangular waves, and sawtooth waves. For each waveform type, it gives the code to generate the waveform signal and output it to a specific memory location. It also notes the required plot settings to view each waveform type.
