ノイズ対策 入力端子

入力端子に、矩形波で3500Hzと20Hzがそれぞれ別の入力設定のピンから入力されます。下記のようなクロック2回分連続で入力されたら正規の信号とするようなもので対応しています。

もっと効果的なFPGAの設定やIP(DSPのFIRフィルタは使えますか?)が有りましたら教えて下さい。宜しくお願いします。​

proc_clk:

PROCESS (clock)

BEGIN

IF clock'EVENT AND clock = '1' THEN

i_1 <= in;

i_2 <= i_1;

END IF;

END PROCESS proc_clk;

i<= i_1 AND i_2 ;

Hi,

 

As I understand it, you have some inquiries related to DSP design implementation. For your information, generally we only address specific inquiries related to FPGA or IP but not design implementation which would more toward design service. Hope you could understand it. However, I will try my best to address to my best knowledge. Sorry as I am not very clear about your target implementation. Would you mind to further elaborate on it? Some illustration would be helpful for better understanding.

 

Please let me know if there is any concern. Thank you.

 

Best regards,

Chee Pin
