$$ \frac{1}{\sqrt{LC}} = 10001 ightarrow LC = 1/100020001$$$$ \frac{R}{L} = 2$$$$ \frac{1}{RC} = 2$$- Here is what I have done but if I [plug the values to WolphramAlpha](https://www.wolframalpha.com/input?i=systems+of+equations+calculator&assumption=%7B%22F%22%2C+%22SolveSystemOf3EquationsCalculator%22%2C+%22equation1%22%7D+-%3E%22x*y+%3D+1%2F100020001%22&assumption=%22FSelect%22+-%3E+%7B%7B%22SolveSystemOf3EquationsCalculator%22%7D%7D&assumption=%7B%22F%22%2C+%22SolveSystemOf3EquationsCalculator%22%2C+%22equation2%22%7D+-%3E%22z%2Fy+%3D+2%22&assumption=%7B%22F%22%2C+%22SolveSystemOf3EquationsCalculator%22%2C+%22equation3%22%7D+-%3E%221%2F%28z*x%29+%3D+2%22)

Band pass filter given cutoff frequency and bandwidth
I have decided to try design a band-pass filter with a cut-off frequency of 10kHz and bandwidth of 2 Hz.  Here is what I have done but if I [plug the values to WolphramAlpha](https://www.wolframalpha.com/input?i=systems+of+equations+calculator&assumption=%7B%22F%22%2C+%22SolveSystemOf3EquationsCalculator%22%2C+%22equation1%22%7D+-%3E%22x*y+%3D+1%2F100020001%22&assumption=%22FSelect%22+-%3E+%7B%7B%22SolveSystemOf3EquationsCalculator%22%7D%7D&assumption=%7B%22F%22%2C+%22SolveSystemOf3EquationsCalculator%22%2C+%22equation2%22%7D+-%3E%22z%2Fy+%3D+2%22&assumption=%7B%22F%22%2C+%22SolveSystemOf3EquationsCalculator%22%2C+%22equation3%22%7D+-%3E%221%2F%28z*x%29+%3D+2%22) it says it doesnt have any solutions.What am I doing wrong?
