Description
  • There are several compression methods for phase to amplitude converter for sine function. In this paper, the linear and parabolic approximation of equi-section division utilizing the symmetry property and amplitude approximation of a sinusoidal waveform for direct digital frequency synthesizer (DDS) and also for other waveform applications, e.g. function generators and telecommunication devices is proposed. The sinusoidal phase from 0 to ?/2 is divided into different numbers of equi-sections. The linear and parabolic approximations are compared. The simulation results show spectral properties of booth approach. The presented sine approximation is usable for FPGA implementation.
