The most general case allows for complex numbers at the input and results in a sequence of equal length, again of complex numbers. The simplest proceeding is probably to compute the higher order derivatives by a FFT on a uniform grid, and use these derivatives to construct local polynomial interpolants which allow the evaluation of the spectrum at arbitrary points $\mathbf{k}_j$. The position of the resistor and capacitor are switched to change from low pass to high pass but the same calculation applies to both filters. 31 Signal Processing. To accurately measure the frequency of a signal, you need a sample rate of at least twice the highest frequency component in the signal.
