i want to design low pass filter on FPGA altera DE2 board....suggest weather i have to use simple input from functional generator or audio input...response will be appricieble...tnx

Input with two different frequency sines would show better graphical view on output, but if You would use real audio, then You have to trust Your ears.

tnx, for response..... 

 what about taking input from mic in..and how ??? suggest me...

Use either a CODEC chip or ADC. Afaik DE2 has CODEC chip and audio input. I'd suggest reading manual of the board.
