Dear all,
Now, there are two sine waves,their frequency are 20Hz and 2000Hz.They can generated by WaveDAC8.Then,I want to modulate them in AM.It is easy to realize that in MATLAB/SIMULINK just by multiplying them.But how to reach it in the CY8CKIT-050? Mixer can only support the modulation about sine wave and square wave,isn't it ?

You could use two tables to gen the two sine waves, using DMA, and multiply the
DMA streams before sending to DAC. Or use DFB assembler to accomplish the
same thing. If the sines are fixed in time and ampliftude just one table with pre-
computed products would do.
