superposition of a square wave over a sine waveHi all,
I am new to VHDL programming. My task is to generate a high frequency square wave(500 Hz) super positioned over a low frequency sine wave(5 Hz). how can this be achieved in VHDL. I know how to generate both these waves separately, but i dunno how to generate them together and superposition them. i would be thankful if someone could help me in this task. even your valuable ideas will be quite useful for me. thanks |

Hi
This site could give you an idea how to make a sinus wave - the sqare shoud be easy, but perhaps will you need some kind of multiplier as well. http://www.jjmk.dk/MMMI/Lessons/11_C..._version_2.htm |
