What information is contained in the lookup table of a direct digital synthesizer (DDS)?
The phase relationship between a reference oscillator and the output waveform
Amplitude values that represent the desired waveform✓Respuesta correcta
The phase relationship between a voltage-controlled oscillator and the output waveform
Frequently used receiver and transmitter frequencies
Explicación
The lookup table stores amplitude values for the desired waveform, normally one full cycle of a sine. Each phase value from the accumulator selects the corresponding amplitude, so the converter can reconstruct the waveform sample by sample.
