ABSTRACT:
A cost effective waveform-generating apparatus that generates accurate and precise waveforms is disclosed. The present waveform-generating apparatus includes a memory for storing a sequence of sampled amplitudes of a waveform, said sampled amplitudes constituting at least two periods of said waveform; a counting circuit, electrically connected to the memory, responsive to a clock signal for generating counting signals; a controlling circuit, electrically connected to the memory and the counting circuit, responsive to the counting signals for controlling the memory to output the sampled amplitudes recurrently; and a digital to analog converter, electrically connected to the memory, for converting the recurrent sampled amplitudes into an analog output.
