Hello,
I have been on the lookout for a high pass or bandpass filter chip. I know there are a lot of low pass filter. but I need send a 5kH communication link, so I would need a bandpass filter with a Fo at
5khz. There are chips like the max274 that can do it, but the steps into designing it seems complex. I am looking either a tutorial on how to set it up or actually a bandpass filter chip from some other companies like linear ... with simpler explanation.
