Abstract

This paper describes the development of an arbitrary function generator based on Direct Digital Synthesis (DDS) technique. This signal generator is capable of generating single-tone sinusoidal (THD <; -80 dBc), two-tone sinusoidal, square wave, triangular and sawtooth waveforms in the frequency range from 0 to 10 kHz. The frequency stability achieved is 3.9 μHz (τ = 2 s) and the amplitude stability is 2.0 μV (τ = 2 s).
