LMC567: Seeking to find a discriminator that works at audio frequencies

richard5998

Part Number: LMC567

I'm trying to source a discriminator covering say 300Hz to 20Khz, that will output a voltage. Do such things exist? Thanks.

P.S. Not sure if I'm posting in the right forum.

Hi Richard,
This device is basically used for a single-tone or narrow bandwidth detection but not a wide bandwidth detection. The typical largest detection bandwidth is 14% of f0. So I don't think it can be used in this application. Could you please help to close this question and post this in Logic forum?
Best regards,
Shawn Zheng

Hi. Okay, thanks for getting back to my question. I will have to do some searching around and see if I can find a product, or maybe I will have to make my own discriminator circuit. Regards. Richard
