Sine Approximation for Direct Digital Frequency Synthesizers and Function Generators
Original language 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 waveformfor 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 linearand parabolic approximations are compared. The simulation results show spectral properties of booth approach. The presented sine approximation is usable for FPGA implementation.
