Currently, I am using PSoC3, CY8C3866LTI-068.  I have a 60Hz analog signal that I am trying to detect low and high peaks.  I have read AN60321, but I am still not sure how to set the mixer values. What type of mixer, LO frequency, and Input Signal Frequency?

   

Is there any other sample peak detector available?

   

Thanks in advance!

60 Hz is mot too fast, you could use an ADC and classify the results. Might be that the PSoC3 is not fast enough, a PSoC5 will be. On a PSoC5 1200 interrupts/s is manageable for building average, min and max.

Thanks, but I won't be able to use psoc5.  Most of our designs are based off psoc3.  What about Sample/Track and hold?  Will loose the accuracy?
