Digital to analog conversion: Digital Audio Foundations

Using an analog oscilloscope, Matt Mayfield proves that digital audio is an accurate, smooth representation of the analog waveform. The anti-aliasing filter in the analog-to-digital converter and the reconstruction filter in the digital-to-analog converter work together to ensure that no frequencies under the Nyquist limit are included in the sample. As a result, the physics of sine waves ensure that the output of the D/A converter is a smooth, exact replica of the sampled band-limited signal.
