How Discrete Signal Interpolation Improves Digital-to-Analog Conversion

Digital Interpolation is a way to reduce complexity and requirements for post-DAC analog filtering. Richard Lyons shows not only how it is done, but also discusses the D-A conversion process itself, what aliasing is and how to handle it, the Nyquist criterion and of course analog filtering. Truly a Tutorial for anyone who wants a clearly to follow explanation of the issues involved.
