Low pass filter realization using VHDL

[Altera_Forum]

Hi all, 

 May I know what should I do in order to design a LPF using VHDL which: a. cutoff frequency fixed at 10 kHz. b. input is from conventional function gen. c. output is observable with conventional oscilloscope.  Please help. Thanks.

Create a design that does the job. Use ADC and DAC for signal acquisition and generation.

Thanks. But it's a little too brief. So meaning I ve to research on ADC and DAC first? 

 May I know how to represent digital filter in mathematical form?

You need to learn DSP techniques first. Start by studying DSP and filters.

Ok. I will read about DSP and filters. After reading abt it, may I know what are the next steps? 

Sorry, I never learn VHDL before.

Then this task is not for You yet. Learn VHDL, learn about filters, learn about DSP, then learn about DSP in VHDL. After these steps You will be able to implement a filter in logic. Start by implementing filters in math software first. E.g. MatLab or MathCad.
