This sample shows different ways of performing Anti-aliasing - both by using only
the native hardware AA support, and by mixing the hardware modes with additional
supersampling. There are various ways in which the supersampled image can be
down-sampled. The way we do the downsampling in this example is the same
technique that was used in 2 of our latest launch demos – “Froggy” and “Adrianne”.
Add myaa.m to your path and enjoy anti-aliased professionally looking graphics in Matlab at any time. Myaa works with any kind of graphic (3-D, plots, scatterplots, ...) and even adds Anti-aliasing to text, ui controls and grids. Myaa is ideal for complex, cluttered and saturated plots.

See attached screenshot for a demonstration. More examples included in the code, just run help myaa .
Curiosa:
For those of you who publish your code often, an undocumented Anti-aliasing option is included in the snapnow.m function in Matlab. To publish a file called test.m you can do:
opts.figureSnapMethod = antialiased
publish( test.m ,opts)
However, you will have more control over the process using myaa, which is also the best choice when using Matlab interactively.
The TW2835 has four high quality NTSC/PAL video decoders, dual color
display controllers and dual video encoders. The TW2835 contains four
built-in analog Anti-aliasing filters, four 10bit Analog-to-Digital converters,
and proprietary digital gain/clamp controller, high quality Y/C separator to
reduce cross-noise and high performance free scaler. Four built-in motion,
Title : Implementation of quadrature modulation and demodulation
Design Object : By implementing quadrature modulation and demodulation of analog signals in digital signal processing, students will have better understanding of sampling and frequency analysis of discrete-time signals.
Design Content : Make a MATLAB function which performs quadrature modulation and demodulation for a input signal with Anti-aliasing filtering.
