Despite there are many filter calculators available on the web, I've still difficulties to translate what I need into calculator design parameters.- For my application, I need ideally a high pass filter that kill everything below 60Hz, and keep everything near 100Hz.
- More mathematically, I would like a HP filter that keep 99% of the signal (voltage) at 90 Hz, and kill x % of the signal at 60Hz (say x = 98%, but I can compromise to reduce the complexity of the filter).
- Other considerations are:
- 1. I don't care of phase distortion
- 2. active filter is OK
- 3. max amplitude of the signal +/- 8V
- 4. very weak current (it is to be the input of an oamp).
- How the real pros would translate these needs into design rules for a calculator?
