Equalizer SoC (Zedboard) based

Good evening to everyone... Could i have some help to build an equalizer based on 12 different filters (4 for the low frequencies, 4 for the medium frequencies and 4 for the high frequencies) ?

Re: Equalizer SoC (Zedboard) based

Have you tried extracting your frequencies using FPGA and then scaling various frequency bands before "reconstructing" the modified signal?

Kind Regards,

Sorry bout that, meant to write FFT, not FPGA. 

Good Luck!

Hello Salvatore.95,

I think you are looking for help on a Zedboard, correct? This forum might not be a good place to ask about this since it deals mostly with the new Community Portal from Xilinx.

I will suggest that going to the following pages with a lot more information about Zedboards.

http://zedboard.org/ - main Zedboard page

http://zedboard.org/projects - projects on Zedboards.

http://zedboard.org/forums/zed-english-forum - and specific forum for the Zedboard

Please let me know if this helps.

Re: Equalizer SoC (Zedboard) based

Hi, if you have a SoC system and you are interested in build a LTV bank filter you can use a IIR type filters . Those filters have a low computational cost and can be easily implemented in C++. One of the main problems is the processing delay between the filters, this delay can affect the filtered signal, to solve this issue you must design your filters with a similar length
