Honored ContributorHi everybody!
I wonder if you can make a sine and triangle wave generator using mega unctions, if so hopefully I can guide on how to do it please. Greetings Edgardo
Honored Contributorthe NCO core will generate sine waves. triangle waves are probably best done in code, its not much more than an accumulator.
Honored ContributorWhy only megafunctions?
What is the sine wave/triangle wave used for? Will you use a DA converter for making the analog signal? What is the maximum frequency? StefaanHonored ContributorI need to generate a sine wave of 50 Hz and a two triangular carriers of about 1.5 kHz to drive inverters. These waves must be compared and will drive the IGBT with the inverter, this is essentially what I need to do.
Greetings from Chile PS: sorry for writing, but I'm using a translator to write the text.Honored ContributorHere is a more complete example of the NCO code, I mentioned in your previous thread. I have used e. g. for 16,7/50 Hz inverter.
Honored ContributorThank you FvM
I will review now and tell you how I was GreetingsHonored ContributorHonored Contributoras in megafunction make sure my sine wave is 50 Hz and algorithm I should use in this case
Large ROM Small ROM CORDIC Multiplier Based I need your help friends, I need guidance. GreetingsHonored Contributorthe different NCO methods have different trade offs as far as resources used (RAM, logic, multipliers). they are explained on page 34 of the NCO User Guide. or you could look at the resource estimation tab in the MegaWizard.
http://www.altera.com/literature/ug/ug_nco.pdf in your case i would choose multiplier-based if you have some available.Honored ContributorI need to generate a sine wave of 50 Hz and a triangular carrier (2 kHz) to drive inverters using Quartus II and Cyclone II device. These waves must be compared and will drive the IGBT with the inverter , this is essentially what I need to do.
